WEBVTT 00:00:22.380 --> 00:00:26.400 MARTINEZ, SANDRA On behalf of NCSD, welcome to today's webinar. 00:00:26.400 --> 00:00:33.140 I'm Sandra Martinez and I asked 102 and the associate I work with is Janet 2. 00:00:33.140 --> 00:00:38.850 Today, I'll be presenting a commodity specific webinar on mechanical bearings, 00:00:38.850 --> 00:00:46.050 specifically bearings, classified within headings 8482 and 8483. 00:00:46.051 --> 00:00:50.368 I will also get into the classification of wheel hub units with bearings. 00:03:04.800 --> 00:03:07.799 MARTINEZ, SANDRA You can also confer with the license broker 00:03:07.800 --> 00:03:12.333 or a trade attorney, and you can also do your research 00:03:12.333 --> 00:03:18.924 of the article researching rulings and cross and decisions from court cases. 00:03:18.925 --> 00:03:21.323 MARTINEZ, SANDRA You actually may find the answer you're looking for, 00:03:21.324 --> 00:03:25.830 or explanations of how we arrived at the classification 00:03:25.830 --> 00:03:31.249 and even sometimes you will see that we revisit the classification 00:03:31.249 --> 00:03:35.975 we originally arrived at because of technology or our consideration 00:03:35.975 --> 00:03:41.131 of technology articles that are mechanical in nature can change, 00:03:41.131 --> 00:03:42.800 and this can affect classification. 00:03:47.300 --> 00:03:50.357 MARTINEZ, SANDRA So even after doing your due diligence 00:03:50.357 --> 00:03:53.986 of conducting research, you may still find that you're unsure 00:03:53.986 --> 00:03:55.528 about the classification. 00:03:55.529 --> 00:03:58.670 MARTINEZ, SANDRA Uh, and if it's for a perspective shipment, 00:03:58.671 --> 00:04:04.070 you can submit a request for a ruling using our E rulings program, 00:04:04.071 --> 00:04:10.467 19 CFR Part 177 explains what the ruling program is about, 00:04:10.468 --> 00:04:15.552 what information is required when filing a ruling and other ruling topics. 00:04:15.553 --> 00:04:20.068 Now, since we're on the topic of submitting a request for a ruling, 00:04:20.069 --> 00:04:26.275 I do wanna mention that when you submit a request, it's always best to send in 00:04:26.276 --> 00:04:28.714 as much information as possible. 00:04:28.715 --> 00:04:31.630 MARTINEZ, SANDRA Uh, for instance, with bearings and other machines. 00:04:31.630 --> 00:04:37.430 It's a good idea to submit technical drawings that are labeled pictures 00:04:37.430 --> 00:04:41.150 or photographs of the item in its application. 00:04:41.150 --> 00:04:45.520 A breakdown of the material composition and a thorough description 00:04:45.520 --> 00:04:47.640 of how the item functions. 00:04:47.640 --> 00:04:51.740 I personally like to see a step by step explanation of its method 00:04:51.740 --> 00:04:57.570 of operation, but the point is the more information you present, 00:04:57.570 --> 00:04:59.220 the better we can understand the good. 00:04:59.220 --> 00:05:02.310 MARTINEZ, SANDRA Which is important when classifying. 00:05:02.310 --> 00:05:05.847 It's always interesting to me when I receive a request 00:05:05.848 --> 00:05:10.649 that just has a picture of the item and it just says, you know, 00:05:10.650 --> 00:05:13.050 generally how the item is used. 00:05:33.888 --> 00:05:35.568 MARTINEZ, SANDRA Here's our disclaimer 00:05:35.568 --> 00:05:38.933 for usages of I'm sorry for usage of images and media. 00:05:38.933 --> 00:05:43.590 This particular webinar has public domain images that are included 00:05:43.590 --> 00:05:45.810 for educational purposes only. 00:05:45.810 --> 00:05:52.930 MARTINEZ, SANDRA So let's jump into the webinar material. 00:05:52.930 --> 00:05:56.320 Mechanical bearings are part of our everyday lives 00:05:56.320 --> 00:05:59.470 and we really don't notice them, but you'll find them 00:05:59.470 --> 00:06:02.430 in almost every machine you can think of. 00:06:02.430 --> 00:06:07.310 They trace back to the Egyptians who used them to move huge stones 00:06:07.310 --> 00:06:08.800 to build pyramids. 00:06:08.800 --> 00:06:13.380 Of course those bearings were thought to be more like plain shaft bearings, 00:06:13.380 --> 00:06:15.290 which we will get into. 00:06:15.290 --> 00:06:19.690 But in regard to their history, it wasn't until the industrial revolution 00:06:19.690 --> 00:06:22.290 that we would see bearings with roller elements. 00:06:22.290 --> 00:06:26.510 MARTINEZ, SANDRA Today both types of bearings play a pivotal role in 00:06:26.510 --> 00:06:30.940 how machines work, particularly since they improved the operation 00:06:30.940 --> 00:06:32.890 and longevity of machines. 00:06:32.890 --> 00:06:38.790 MARTINEZ, SANDRA So I mentioned that there are different types 00:06:38.790 --> 00:06:43.710 of antifriction bearings actually for classification purposes. 00:06:43.710 --> 00:06:44.190 There are two types. 00:06:45.300 --> 00:06:49.740 MARTINEZ, SANDRA Those that use a rolling mechanism to reduce friction 00:06:49.740 --> 00:06:52.910 and bearings that do not incorporate roller elements, 00:06:52.910 --> 00:06:57.310 but instead they have a surface with oil or a fluid, 00:06:57.310 --> 00:07:00.520 and then that creates a smooth sliding surface. 00:07:05.793 --> 00:07:09.310 MARTINEZ, SANDRA In classifying articles, we apply the general rules 00:07:09.310 --> 00:07:14.520 of interpretation the Gris, and we begin with GRI, one which, 00:07:14.520 --> 00:07:17.510 for legal purposes, states the classification 00:07:17.510 --> 00:07:22.460 of articles shall be determined according to the terms of the heading. 00:07:22.460 --> 00:07:28.570 Any relative section or chapter notes, and unless otherwise stated according 00:07:28.570 --> 00:07:33.510 to the remaining gerris, in order the first type of bearing, 00:07:33.510 --> 00:07:36.360 we will look into our bearings that are classified within. 00:07:36.360 --> 00:07:41.080 MARTINEZ, SANDRA Heading 8482, which, if you think 00:07:41.080 --> 00:07:47.080 in terms of the heading, provides for antifriction ball or roller bearings, 00:07:47.080 --> 00:07:51.520 it should be recognized that these bearings are not housed or installed 00:07:51.520 --> 00:07:52.790 into a frame. 00:07:52.790 --> 00:07:58.320 Those types of bearings are classified somewhere else outside of heading 8482. 00:08:03.382 --> 00:08:06.860 MARTINEZ, SANDRA Here's an explanation of the critical components 00:08:06.860 --> 00:08:08.360 that make up a bearing. 00:08:08.360 --> 00:08:11.740 You have the inner and outer races. 00:08:11.740 --> 00:08:16.570 These are the surfaces or tracks where the rolling elements make contact. 00:08:16.570 --> 00:08:20.850 As you can see, the inner race is the smaller of the two. 00:08:20.850 --> 00:08:25.240 You also have the cage which is referred to as a retainer. 00:08:25.240 --> 00:08:29.933 The retainer functions as a holder for loose rolling elements. 00:08:29.933 --> 00:08:33.110 MARTINEZ, SANDRA And it keeps the roller elements positioned 00:08:33.110 --> 00:08:35.390 or aligned along the races. 00:08:37.054 --> 00:08:39.090 MARTINEZ, SANDRA It also functions as a separator 00:08:39.090 --> 00:08:40.910 that provides the required spacing. 00:08:40.910 --> 00:08:46.240 MARTINEZ, SANDRA You will also see rolling elements installed 00:08:46.240 --> 00:08:51.070 between the races, which in this picture are ball elements. 00:08:51.070 --> 00:08:54.680 The configuration of the element changes with roller bearings. 00:08:57.055 --> 00:08:59.920 MARTINEZ, SANDRA There are additional components that may be used 00:08:59.920 --> 00:09:00.950 with bearings. 00:09:00.950 --> 00:09:05.680 For instance, there's a shield which prevents larger particles from entering, 00:09:05.680 --> 00:09:10.640 and it also keeps the grease within, and you can see a circlip 00:09:10.640 --> 00:09:13.930 which keeps the shield in panel in place. 00:09:13.930 --> 00:09:16.470 A very common place where you will find bearings 00:09:16.470 --> 00:09:19.770 with the shield is a bicycle and those. 00:09:19.770 --> 00:09:24.070 MARTINEZ, SANDRA Well, some of those are called cartridge bearings. 00:09:24.070 --> 00:09:27.970 The interesting part about cartridge bearings is there are constructed 00:09:27.970 --> 00:09:34.280 to be a complete unit and that cannot be adjusted or fully dissembled. 00:09:34.280 --> 00:09:38.660 But the good news about that is that there are fairly inexpensive 00:09:38.660 --> 00:09:43.730 and so this balances out there inability to be deconstructed. 00:09:45.480 --> 00:09:47.940 MARTINEZ, SANDRA Ohh, by the way, some bearings have seals 00:09:47.940 --> 00:09:51.200 which are not pictured here and seals are used 00:09:51.200 --> 00:09:53.760 to keep like the finer particles from entering. 00:09:58.666 --> 00:10:02.750 MARTINEZ, SANDRA So function wise there are two primary ones. 00:10:02.750 --> 00:10:07.450 They reduce friction and they fix guide or hold components 00:10:07.450 --> 00:10:12.400 in place while they are transferring or modifying energy. 00:10:12.400 --> 00:10:16.370 This makes sense because the job of a bearing is to provide support 00:10:16.370 --> 00:10:22.240 to rotating shafts or machine parts while simultaneously allowing them 00:10:22.240 --> 00:10:24.210 to have free and smooth movement. 00:10:29.562 --> 00:10:32.400 MARTINEZ, SANDRA So bearings are used in most machines 00:10:32.400 --> 00:10:35.200 or applications where there's a shaft. 00:10:35.200 --> 00:10:39.740 In addition, they're used in applications where energy is created, 00:10:39.740 --> 00:10:43.160 machining is done, and materials are created. 00:10:45.308 --> 00:10:46.930 MARTINEZ, SANDRA And so I want to mention that 00:10:46.930 --> 00:10:50.550 because there are a variety of applications for bearings, 00:10:50.550 --> 00:10:53.560 you know it's no surprise that they can be made of material other than metal. 00:10:55.185 --> 00:10:58.240 MARTINEZ, SANDRA So, like for practical reasons, a plastic bearing 00:10:58.240 --> 00:11:03.620 may be used in saltwater applications due to harsh chemicals. 00:11:03.620 --> 00:11:06.730 MARTINEZ, SANDRA Uh sapphire bearings have been used in watches 00:11:06.730 --> 00:11:12.070 and with sensitive measuring instruments such as compasses and gyroscopes. 00:11:12.070 --> 00:11:16.070 MARTINEZ, SANDRA The advantage with this is these bearings are used 00:11:16.070 --> 00:11:22.330 in high accuracy capacities as they tend to be small in size and weight. 00:11:22.330 --> 00:11:25.490 MARTINEZ, SANDRA And because they're small in size, they can be brittle, 00:11:25.490 --> 00:11:28.150 and for that reason you might find them used with a housing. 00:11:30.338 --> 00:11:33.070 MARTINEZ, SANDRA And in addition, bearings can be made 00:11:33.070 --> 00:11:38.270 of ceramic material which are used in these high temperature applications, 00:11:38.270 --> 00:11:42.290 but as ceramic ball bearing is not the same as a metal bearing 00:11:42.290 --> 00:11:44.760 that has been coated with a ceramic material. 00:11:46.550 --> 00:11:50.510 MARTINEZ, SANDRA Nevertheless, bearings can also be a bronze 00:11:50.510 --> 00:11:52.750 or copper materials. 00:11:52.750 --> 00:11:55.403 However, the most common type of material 00:11:55.404 --> 00:11:57.550 to manufacture bearings is steel. 00:12:01.555 --> 00:12:04.450 MARTINEZ, SANDRA So let's talk about the method of operation. 00:12:04.450 --> 00:12:06.500 For ball or roller bearings. 00:12:06.500 --> 00:12:10.160 Basically the balls or rollers move within the races. 00:12:10.160 --> 00:12:14.960 It's the balls or rollers that endure or bear the load, 00:12:14.960 --> 00:12:18.050 and this allows the bearing to spin smoothly, 00:12:18.050 --> 00:12:22.400 which in turn allows the components or the machinery parts 00:12:22.400 --> 00:12:25.980 to which they're installed onto to to rotate or move 00:12:25.980 --> 00:12:27.290 in their appropriate motion. 00:12:32.688 --> 00:12:36.330 MARTINEZ, SANDRA So here we have 4 main questions to ask 00:12:36.330 --> 00:12:38.580 when classifying bearings. 00:12:38.580 --> 00:12:42.270 Does the bearing support an axial or radial load? 00:12:43.309 --> 00:12:46.660 MARTINEZ, SANDRA Does the bearing have linear or roller motion? 00:12:47.660 --> 00:12:50.980 MARTINEZ, SANDRA What is the material composition of the bearing 00:12:50.980 --> 00:12:53.410 and what are the dimensions of the bearing? 00:12:57.691 --> 00:13:00.530 MARTINEZ, SANDRA So in the previous slide I just mentioned 00:13:00.530 --> 00:13:05.890 that the dimensions of a bearing are needed for classification purposes, 00:13:05.890 --> 00:13:08.650 particularly some of the subheadings. 00:13:08.650 --> 00:13:13.260 Here's a diagram that explains how the outside diameter, 00:13:13.260 --> 00:13:17.070 width and internal diameter are measured. 00:13:17.070 --> 00:13:20.100 They're pretty basic measurements that you can use with a ruler, 00:13:20.100 --> 00:13:24.290 but for more accurate measurements you can use a vernier caliper, 00:13:24.290 --> 00:13:28.450 but of course the manufacturer should be able to provide these dimensions. 00:13:28.450 --> 00:13:32.990 MARTINEZ, SANDRA Very often the bearing has a specific application 00:13:32.990 --> 00:13:36.790 and will have been designed to fit that application so. 00:13:36.790 --> 00:13:38.920 MARTINEZ, SANDRA You know the manufacturer 00:13:38.920 --> 00:13:42.000 should have that technical information for you. 00:13:42.000 --> 00:13:51.120 MARTINEZ, SANDRA The subheading breakouts within heading 8482 began 00:13:51.120 --> 00:13:52.410 with ball bearings. 00:13:52.410 --> 00:13:55.746 With integral shots, integral shot bearings 00:13:55.747 --> 00:13:58.400 are generally double row bearings. 00:13:58.400 --> 00:14:01.680 The shaft function as an inner race of the bearing 00:14:01.680 --> 00:14:06.000 or typically the inner race, is machine directly onto the surface 00:14:06.000 --> 00:14:07.850 of the internal shaft. 00:14:07.850 --> 00:14:11.560 This is different from conventional bearings within a races. 00:14:11.560 --> 00:14:16.730 These types of bearings were originally used with water pumps of motor vehicles. 00:14:16.730 --> 00:14:19.560 MARTINEZ, SANDRA But they can now be found in other types 00:14:19.560 --> 00:14:20.810 of pumps and machines. 00:14:21.880 --> 00:14:25.980 You may even find them used in a track system of our garage door. 00:14:31.332 --> 00:14:33.810 MARTINEZ, SANDRA So ball bearings without an integral shape 00:14:33.810 --> 00:14:40.930 or provided for within subheading 8480, two 10:50, and they're classified 00:14:40.930 --> 00:14:42.990 by their configuration. 00:14:42.990 --> 00:14:47.240 Now some headings will require the measurement of the outside diameter 00:14:47.240 --> 00:14:50.620 as I mentioned, but they'll call for it in millimeters. 00:14:50.620 --> 00:14:54.120 So if it they give you that information in inches, you'll have 00:14:54.120 --> 00:14:55.110 to make the conversion. 00:14:59.821 --> 00:15:00.370 MARTINEZ, SANDRA OK. 00:15:00.370 --> 00:15:04.690 And following the sequence of the 8482 subheadings, 00:15:04.690 --> 00:15:12.190 we now have subheading eighty 480-210-5004, which is a specifics 00:15:12.190 --> 00:15:15.690 of heading that provides for unground ball bearings. 00:15:15.690 --> 00:15:19.020 It's typically the races that have not been grounded, 00:15:19.020 --> 00:15:22.590 I'm sorry, grinded or hardened with these types of bearings. 00:15:22.590 --> 00:15:27.700 It's our understanding that the Raceway is a critical load bearing service 00:15:27.700 --> 00:15:30.560 and it's the section of the bearing that's significantly. 00:15:30.560 --> 00:15:33.400 MARTINEZ, SANDRA Impacts how it functions. 00:15:33.400 --> 00:15:35.995 One way to know if you have an unfinished varying 00:15:35.996 --> 00:15:37.240 is when you look at it. 00:15:37.240 --> 00:15:39.540 It kind of has a dull finish. 00:15:39.540 --> 00:15:42.620 They're not polished looking and you can find them 00:15:42.620 --> 00:15:47.790 in less demanding applications such as bicycles, lawn mowers, 00:15:47.790 --> 00:15:49.610 shopping carts, and even casters. 00:15:55.212 --> 00:15:57.890 MARTINEZ, SANDRA So next we talk about thrust bearings, 00:15:57.890 --> 00:16:02.070 which are used in places where axial loads predominate, 00:16:02.070 --> 00:16:04.770 such as the propellers of ships. 00:16:04.770 --> 00:16:08.260 So when you think about the propeller, it makes sense 00:16:08.260 --> 00:16:12.880 that a thrust bearing is used because they turn and they push the ship forward 00:16:12.880 --> 00:16:16.250 with massive thrust acting on the propeller shaft, 00:16:16.250 --> 00:16:18.930 the thrust ball bearing reduces friction. 00:16:19.774 --> 00:16:22.460 MARTINEZ, SANDRA And it minimizes the wear on the shaft 00:16:22.460 --> 00:16:24.600 and the components that glide on the bearing. 00:16:28.960 --> 00:16:31.960 MARTINEZ, SANDRA And these are the different types of thrust bearings. 00:16:31.960 --> 00:16:35.780 You have the flat race, a single direction 00:16:35.780 --> 00:16:38.900 and double direction thrust barbarian. 00:16:38.900 --> 00:16:43.240 The type that will be used really depends on the application, 00:16:43.240 --> 00:16:47.150 and that can range anywhere from vehicle gearboxes 00:16:47.150 --> 00:16:54.250 that use helical gears, turbines, industrial machinery to machinery used 00:16:54.250 --> 00:16:56.080 in mining and construction. 00:16:57.100 --> 00:16:59.790 Thrust bearings have also been used with radio. 00:16:59.790 --> 00:17:01.390 MARTINEZ, SANDRA Antenna masts. 00:17:01.390 --> 00:17:05.333 It helps reduce the load on the antenna rotator. 00:17:10.130 --> 00:17:13.140 MARTINEZ, SANDRA Next, we have linear ball bearings classified 00:17:13.140 --> 00:17:16.460 within subheading 8482. 00:17:16.460 --> 00:17:18.933 Ten 5012. 00:17:19.370 --> 00:17:22.560 They're designed to support loads that move along a straight line. 00:17:23.900 --> 00:17:28.610 MARTINEZ, SANDRA These bearings are normally used in precision machinery, 00:17:28.610 --> 00:17:31.795 medical instruments, agriculture equipment, 00:17:31.796 --> 00:17:34.400 and automated production equipment, 00:17:34.400 --> 00:17:37.960 and this makes perfect sense because machines in these applications 00:17:37.960 --> 00:17:41.370 often have a forward and backward motion. 00:17:42.700 --> 00:17:45.160 MARTINEZ, SANDRA I will say that these types of bearings, 00:17:45.160 --> 00:17:49.850 from my understanding, are not too too too challenging to install 00:17:49.850 --> 00:17:52.350 and they require minimum maintenance. 00:17:56.667 --> 00:18:00.050 MARTINEZ, SANDRA Here's another type of linear ball bearing, also 00:18:00.050 --> 00:18:03.150 known as linear motion guides. 00:18:03.150 --> 00:18:07.780 These types of linear ball bearings are guideways, 00:18:07.780 --> 00:18:11.980 and they provide linear motion by recirculating rolling elements 00:18:11.980 --> 00:18:16.230 between a profiled rail and a bearing block. 00:18:16.230 --> 00:18:21.950 They can be used with overhead transport systems, gantry robots, 00:18:21.950 --> 00:18:26.770 machine tool, table tops, and even linear actuators. 00:18:31.309 --> 00:18:34.070 MARTINEZ, SANDRA OK, moving through the subheading sequence. 00:18:34.070 --> 00:18:38.430 Uh, next of topic or angular contact bearings. 00:18:38.430 --> 00:18:42.610 The uniqueness of these bearings are that they accommodate radial 00:18:42.610 --> 00:18:44.270 and axial loads. 00:18:44.270 --> 00:18:45.580 They're considered to be directional. 00:18:46.564 --> 00:18:49.950 MARTINEZ, SANDRA They're known as spindle bearings, and they tend 00:18:49.950 --> 00:18:52.080 to have a high speed rating. 00:18:52.080 --> 00:18:56.100 They're designed so that the weight of the load is transferred 00:18:56.100 --> 00:19:03.070 from one shoulder to the other through the balls along specific contact angles. 00:19:03.070 --> 00:19:06.610 You can see this with the raised shoulders that are highlighted 00:19:06.610 --> 00:19:09.120 by the blue arrows in the picture. 00:19:09.120 --> 00:19:14.810 The angle of the contact in both the inner and outer race is the same. 00:19:16.255 --> 00:19:18.490 MARTINEZ, SANDRA And so because of their configuration, 00:19:18.491 --> 00:19:22.749 they're not intended to intended to be like dismantled, 00:19:22.750 --> 00:19:25.030 but instead they're replaced. 00:19:25.030 --> 00:19:28.140 And applications for these types of bearings are. 00:19:29.367 --> 00:19:31.850 MARTINEZ, SANDRA We all have units of automobiles. 00:19:31.850 --> 00:19:37.490 Uh vacuum pumps, centrifuges, tool spindles and heavy machinery. 00:19:38.724 --> 00:19:41.940 MARTINEZ, SANDRA And of course, you can probably find them in bicycles. 00:19:46.221 --> 00:19:48.470 MARTINEZ, SANDRA Radio ball bearings are classified 00:19:48.470 --> 00:19:59.560 between subheadings eighty 480-210-5032 and 8482 ten 5064 radio ball bearings 00:19:59.560 --> 00:20:05.520 typically transfer transfer radial loads to the access of the shaft. 00:20:05.520 --> 00:20:10.380 They are known to be the most common type of bearing since they are versatile 00:20:10.380 --> 00:20:15.070 and they can tolerate higher speeds and also because they're pretty durable. 00:20:16.187 --> 00:20:18.910 MARTINEZ, SANDRA There are two basic types of radial ball bearings. 00:20:18.910 --> 00:20:25.740 You have the non filling type, the Conrad type or the maximum capacity type 00:20:25.740 --> 00:20:30.610 and the full capacity types of bearings are filling slot bearings 00:20:30.610 --> 00:20:34.220 that have raises that allow for more balls to be loaded. 00:20:38.165 --> 00:20:41.420 MARTINEZ, SANDRA Whereas the Conrad ball bearings, also 00:20:41.420 --> 00:20:47.010 known as deep groove ball bearings, they can tolerate higher load ratings, 00:20:47.010 --> 00:20:51.730 but they're less tolerant of misalignment between the raises. 00:20:51.730 --> 00:20:56.050 These types of bearings are assembled by offsetting the inner 00:20:56.050 --> 00:21:01.450 and outer races so that their races touch it one point and then 00:21:01.450 --> 00:21:06.490 on the other side you have a gap and the ball elements are inserted 00:21:06.490 --> 00:21:07.370 into the large gap. 00:21:07.370 --> 00:21:10.740 MARTINEZ, SANDRA And distributed around the bearing assembly. 00:21:10.740 --> 00:21:14.075 MARTINEZ, SANDRA The act of distributing the balls 00:21:14.076 --> 00:21:17.680 uh causes the inner and outer races to be concentric now. 00:21:17.680 --> 00:21:22.390 MARTINEZ, SANDRA If the ball elements were left to move freely, 00:21:22.390 --> 00:21:25.790 the balls could resume their offset locations 00:21:25.790 --> 00:21:29.480 and the bearing could basically disassemble itself and so 00:21:29.480 --> 00:21:34.720 for this reason you'll find a cage is inserted and tends to be riveted 00:21:34.720 --> 00:21:39.050 in place to hold the balls, and they're distributed positions. 00:21:42.863 --> 00:21:45.298 MARTINEZ, SANDRA So we're now pivoting from ball bearings 00:21:45.299 --> 00:21:47.380 to roller bearings. 00:21:47.380 --> 00:21:50.410 Roller bearings do have the same function as ball bearings. 00:21:50.410 --> 00:21:55.060 The biggest difference between the two is the shape of the roller elements. 00:21:55.060 --> 00:21:58.550 For roller bearings, the roller elements can be needle, 00:21:58.550 --> 00:22:00.900 spherical and even cylinder shape. 00:22:02.010 --> 00:22:05.550 These types of bearings can carry heavy loads when dealing 00:22:05.550 --> 00:22:09.590 with misalignments and shaft deflections. 00:22:09.590 --> 00:22:12.720 And so that's why they're often used with like power machines. 00:22:13.626 --> 00:22:16.570 MARTINEZ, SANDRA The reason being is that the design allows for loads 00:22:16.570 --> 00:22:20.670 to be distributed over large surface compared to the ball bearings. 00:22:21.975 --> 00:22:26.300 MARTINEZ, SANDRA Therefore, they can handle heavy combined radial 00:22:26.300 --> 00:22:28.160 and thrust loads. 00:22:28.160 --> 00:22:31.990 One other way that ruling roller bear is differ from ball bearings, 00:22:31.990 --> 00:22:34.900 and that it's that it's more likely that they can be. 00:22:35.736 --> 00:22:38.660 MARTINEZ, SANDRA Disassembled and their parts can be replaced 00:22:38.660 --> 00:22:40.790 when compared to ball bearings. 00:22:49.454 --> 00:22:53.040 MARTINEZ, SANDRA So here are illustrations of roller elements used 00:22:53.040 --> 00:22:54.490 in roller bearings. 00:22:54.490 --> 00:22:57.750 And of course you can see how they differ in shape 00:22:57.750 --> 00:23:00.540 from ball bearings and even each other. 00:23:00.540 --> 00:23:03.590 It's important to know the shape of the roller bearing 00:23:03.590 --> 00:23:06.710 or the roller element really, as this will determine 00:23:06.710 --> 00:23:09.860 which subheading is appropriate as you move along 00:23:09.860 --> 00:23:13.150 through these roller bearing subheadings. 00:23:18.502 --> 00:23:21.970 MARTINEZ, SANDRA So tapered roller bearings have been around a long time. 00:23:21.970 --> 00:23:23.340 Uh, for their race makeup. 00:23:23.340 --> 00:23:27.230 They have a cup that functions as an outer race and a cone unit 00:23:27.230 --> 00:23:30.580 that has the roller elements and the inner race. 00:23:30.580 --> 00:23:33.490 MARTINEZ, SANDRA They're used in motor vehicles 00:23:33.490 --> 00:23:36.520 and in particular the wheel hub units of cars and machines. 00:23:37.473 --> 00:23:40.320 MARTINEZ, SANDRA In wheel hub units, you can usually find them used 00:23:40.320 --> 00:23:43.340 in pairs facing opposite direction. 00:23:43.340 --> 00:23:47.470 This way they can bear the thrust loads in both directions. 00:23:47.470 --> 00:23:50.520 They are the most common type of roller bearing. 00:23:51.434 --> 00:23:54.130 MARTINEZ, SANDRA 01 more thing it should be mentioned 00:23:54.130 --> 00:23:57.380 that there is a subheading breakout when the cup 00:23:57.380 --> 00:24:02.940 and cones are entered as a set and a separate subheading 00:24:02.940 --> 00:24:06.870 for when the cone is entered separate from the cup 00:24:06.870 --> 00:24:09.680 and the Cup when entered separate would be classified as a part. 00:24:15.618 --> 00:24:18.900 MARTINEZ, SANDRA Spherical roller bearings, as their name indicates, 00:24:18.900 --> 00:24:23.200 have spherical or barrel shaped rollers. 00:24:23.200 --> 00:24:26.073 The 10 digit classification is determined 00:24:26.074 --> 00:24:29.990 on whether the bearing is a single row or not. 00:24:29.990 --> 00:24:34.340 These bearings are particularly useful in supporting a rotating shots 00:24:34.340 --> 00:24:38.760 that is inserted into the bore of the inner ring and maybe misaligned 00:24:38.760 --> 00:24:43.710 with regards to the outer ring and featuring this capability, 00:24:43.710 --> 00:24:46.350 you know it's no surprise that these types of bearings. 00:24:46.350 --> 00:24:49.360 MARTINEZ, SANDRA Are primarily used in applications 00:24:49.360 --> 00:24:52.590 where you have an angular misalignment. 00:24:52.590 --> 00:24:56.180 They're designed to resist heavy and shock loads 00:24:56.180 --> 00:25:01.600 and so they can even be doubled up to receive the thrust in either direction. 00:25:06.961 --> 00:25:09.711 MARTINEZ, SANDRA Needle roller bearings are often used 00:25:09.712 --> 00:25:12.285 in motor vehicles and mostly in transmissions 00:25:12.286 --> 00:25:15.250 and compressors of motor vehicles. 00:25:15.250 --> 00:25:20.440 But to be considered a needle roller bearing for classification purposes, 00:25:20.440 --> 00:25:24.300 subheading note 4 to chapter 84 must be met. 00:25:25.430 --> 00:25:29.920 The note is for bearings with cylindrical rollers. 00:25:29.920 --> 00:25:34.600 However, the cylindrical rollers must have a uniform diameter 00:25:34.600 --> 00:25:35.070 that does not exceed. 00:25:35.070 --> 00:25:39.080 MARTINEZ, SANDRA 5 millimeters and it features a length 00:25:39.080 --> 00:25:42.310 that is at least three times the measure diameter. 00:25:43.404 --> 00:25:45.750 MARTINEZ, SANDRA If these parameters are met, 00:25:45.750 --> 00:25:48.133 the cylindrical bearing can be classified 00:25:48.133 --> 00:25:54.570 within subheading eighty 480-240-0000. 00:25:54.570 --> 00:25:56.580 And if you think about it, it makes sense 00:25:56.580 --> 00:25:59.840 because it's these measurement parameters that allow the rollers 00:25:59.840 --> 00:26:00.690 to be elongated. 00:26:04.635 --> 00:26:05.560 MARTINEZ, SANDRA Now. 00:26:05.560 --> 00:26:09.050 MARTINEZ, SANDRA If the cylindrical roller does not meet the specifics 00:26:09.050 --> 00:26:12.960 of Note 4 to chapter 84, the bearing would be classified 00:26:12.960 --> 00:26:19.100 in subheading eighty, 480-250-0000, which provides 00:26:19.100 --> 00:26:21.150 for other cylindrical bearings. 00:26:21.150 --> 00:26:23.040 MARTINEZ, SANDRA Umm, usually. 00:26:23.040 --> 00:26:27.730 Cylindrical bearings can only manage a limited amount of thrust load, 00:26:27.730 --> 00:26:31.980 and this is an operational difference between the cylindrical 00:26:31.980 --> 00:26:36.833 and needle roller bearings, which can handle very high radial loads. 00:26:41.433 --> 00:26:43.109 MARTINEZ, SANDRA OK, parts of bearings. 00:26:43.110 --> 00:26:47.700 So when classifying parts of bearings and for that matter any machine 00:26:47.700 --> 00:26:53.770 of chapter 84, we look to Note 2 to section 16 and we apply it 00:26:53.770 --> 00:27:00.800 in a hierarchy manner and it's simplest version part A to Note 2 says that 00:27:00.800 --> 00:27:07.360 if an item is provided for Euro nominee or has a function that meets the terms 00:27:07.360 --> 00:27:12.580 of the the heading then the item should be classified in its respective heading. 00:27:15.588 --> 00:27:20.080 MARTINEZ, SANDRA If the item is not specifically provided for 00:27:20.080 --> 00:27:25.230 and no data is not applicable, we then fall to note B, which says 00:27:25.230 --> 00:27:30.030 if the item is specifically or principally used with a particular kind 00:27:30.030 --> 00:27:33.230 of machine, then it's classified as a part within that heading. 00:27:34.988 --> 00:27:39.430 MARTINEZ, SANDRA So when you're considering parts or components 00:27:39.430 --> 00:27:44.030 of an antifriction bearing, we don't usually have to go further than OB, 00:27:44.030 --> 00:27:47.400 but I've included it note C just to give you a complete view 00:27:47.400 --> 00:27:48.120 of the note. 00:27:48.120 --> 00:27:50.910 It's always good to understand these notes in their entire team. 00:27:56.176 --> 00:27:58.340 MARTINEZ, SANDRA So with parts of bearings, 00:27:58.340 --> 00:28:02.160 a subheading 8482 ninety one provides for. 00:28:03.230 --> 00:28:06.320 MARTINEZ, SANDRA Balls, needles and rollers. 00:28:06.320 --> 00:28:09.560 MARTINEZ, SANDRA But with a steel ball elements, 00:28:09.560 --> 00:28:13.880 a deeper consideration has to be taken because of note 6 00:28:13.880 --> 00:28:19.340 to chapter 84, which states that for steel balls the maximum 00:28:19.340 --> 00:28:26.260 and minimum diameters can differ from the nominal diameter by more than 1% 00:28:26.260 --> 00:28:31.250 or by more than .05 millimeters whichever's less. 00:28:31.250 --> 00:28:34.133 Otherwise it's excluded from being classified 00:28:34.133 --> 00:28:37.130 as a part within heading 8482. 00:28:38.100 --> 00:28:40.020 MARTINEZ, SANDRA Just a side note, uh, 00:28:40.020 --> 00:28:42.514 a nominal ball diameter is the value used 00:28:42.515 --> 00:28:46.740 to make like a general identification of the ball size. 00:28:46.740 --> 00:28:49.330 Nevertheless, in case you're asking yourself, 00:28:49.330 --> 00:28:51.490 where would I get that information? 00:28:51.490 --> 00:28:54.513 Well, that's something that the manufacturer will probably have 00:28:54.514 --> 00:28:55.520 to provide. 00:28:55.520 --> 00:28:58.450 It ties into the molding specs of the ball 00:28:58.450 --> 00:29:01.750 and the manufacturer will be the party to have that information. 00:29:06.883 --> 00:29:11.070 MARTINEZ, SANDRA So subheading 84, eighty 299 provides for the inner 00:29:11.070 --> 00:29:15.520 and outer races, including the cups for tapered roller bearings. 00:29:15.520 --> 00:29:17.890 MARTINEZ, SANDRA Other components that are classified 00:29:17.890 --> 00:29:22.670 within the subheading are cages and fixing sleeves. 00:29:24.700 --> 00:29:25.870 MARTINEZ, SANDRA Oh, just one thing. 00:29:25.870 --> 00:29:31.570 Uh vulcanized rubber seals are excluded from heading 8482. 00:29:31.570 --> 00:29:36.360 Well, all of Chapter 84 based on note 18 to section 16. 00:29:41.048 --> 00:29:42.970 MARTINEZ, SANDRA So as I mentioned, fixing sleeves 00:29:42.970 --> 00:29:46.900 for bearings are classified as parts of a bearing. 00:29:46.900 --> 00:29:48.970 MARTINEZ, SANDRA Uh, why, right? 00:29:48.970 --> 00:29:49.870 Why would those? 00:29:49.870 --> 00:29:53.290 They're not actually any of the parts that I showed you earlier wired. 00:29:53.290 --> 00:29:56.280 Those considered parts of a bearing. 00:29:56.280 --> 00:30:02.920 Well, ruling 967092 gives us some insight by explaining 00:30:02.920 --> 00:30:07.770 that fixing sleeves are used to mount and help align bearing 00:30:07.770 --> 00:30:09.160 when mounted onto a shaft. 00:30:10.240 --> 00:30:14.300 It's thought that they basically assist in the positioning 00:30:14.300 --> 00:30:16.250 and operation of a bearing. 00:30:16.250 --> 00:30:20.720 MARTINEZ, SANDRA And so, because of this, uh, fixing sleeves are considered 00:30:20.720 --> 00:30:24.340 to be parts of a bearing for classification purposes though. 00:30:29.499 --> 00:30:32.100 MARTINEZ, SANDRA OK, we've now arrived to the aspect 00:30:32.100 --> 00:30:37.250 of the presentation that discusses bearing housings, house bearings 00:30:37.250 --> 00:30:42.990 and plain chef bearings, which are all classified within heading 8483. 00:30:47.045 --> 00:30:53.380 MARTINEZ, SANDRA Subheading 8483.20 provides for house bearings. 00:30:53.380 --> 00:31:00.170 These are bearings that are pressed or inserted into a housing or frame. 00:31:00.170 --> 00:31:03.790 They come in different shapes and configurations. 00:31:03.790 --> 00:31:06.680 I've even heard them refer to as cartridges. 00:31:06.680 --> 00:31:08.000 MARTINEZ, SANDRA On and. 00:31:08.000 --> 00:31:10.731 So that's why you have the the two breakouts, 00:31:10.732 --> 00:31:12.630 one or for the more common one, 00:31:12.630 --> 00:31:15.890 and the ones that in case you know, they've come 00:31:15.891 --> 00:31:17.820 in some other configuration. 00:31:18.767 --> 00:31:22.820 MARTINEZ, SANDRA And So what is the purpose of a housing for a bearing? 00:31:22.820 --> 00:31:26.870 Well, they support the motion of the bearing and they act 00:31:26.870 --> 00:31:29.700 as a customized mounting for it. 00:31:29.700 --> 00:31:34.290 It also protects the bearing from contaminants, and this is beneficial 00:31:34.290 --> 00:31:36.720 because it extends the life of the bearing. 00:31:41.712 --> 00:31:43.050 MARTINEZ, SANDRA So here are some pictures 00:31:43.051 --> 00:31:45.940 of bearing housings. 00:31:45.940 --> 00:31:48.070 MARTINEZ, SANDRA Me and my pointer here. 00:31:48.070 --> 00:31:50.680 Uh, this upper left picture. 00:31:51.567 --> 00:31:52.990 MARTINEZ, SANDRA Is to give you an idea of 00:31:52.990 --> 00:31:57.180 what a flange housing would look like, and over here 00:31:57.180 --> 00:32:01.280 on the upper right picture we have a take up housing. 00:32:03.880 --> 00:32:07.030 MARTINEZ, SANDRA And on this bottom left, right here. 00:32:07.030 --> 00:32:10.790 MARTINEZ, SANDRA We have a pillow block housing 00:32:10.790 --> 00:32:14.120 and right here the bottom right picture is that 00:32:14.120 --> 00:32:16.860 of a miniature pillow block housing. 00:32:24.352 --> 00:32:27.046 MARTINEZ, SANDRA Here's a cutaway illustration. 00:32:28.167 --> 00:32:31.020 MARTINEZ, SANDRA That depicts what a housing with a bearing looks like 00:32:31.020 --> 00:32:33.470 if taken apart or dissembled. 00:32:33.470 --> 00:32:37.190 I really like this one because you can see the bearing separate 00:32:37.190 --> 00:32:38.760 from the housing. 00:32:38.760 --> 00:32:42.600 The housing itself is not functioning as a race for the bearing, 00:32:42.600 --> 00:32:45.910 and this is what makes it differ from a wheel hub unit, 00:32:45.910 --> 00:32:47.980 which we'll get into in just a bit. 00:32:47.980 --> 00:32:51.750 But I mean, you can clearly see that the bearing is separate from the housing. 00:32:53.219 --> 00:32:57.460 MARTINEZ, SANDRA Ohh, by the way, you can also see a fixing sleeve 00:32:57.460 --> 00:32:59.700 which here is referred to as an adapter. 00:33:05.513 --> 00:33:09.470 MARTINEZ, SANDRA So these subheadings listed in this slide primarily provide 00:33:09.470 --> 00:33:11.390 for only the bearing housings. 00:33:11.390 --> 00:33:14.360 In other words, there's no bearing press inside. 00:33:14.360 --> 00:33:19.730 However, subheading 8483 thirty 80 does have a statistical breakout 00:33:19.730 --> 00:33:22.220 for housings with plain shaft bearings. 00:33:28.025 --> 00:33:30.040 MARTINEZ, SANDRA OK, plain shaft bearings. 00:33:30.040 --> 00:33:35.380 Plain shaft bearings are also referred to as slide contact bearings, 00:33:35.380 --> 00:33:40.840 sleeve bearings, journal bearings, or even by the trade term bushings. 00:33:40.840 --> 00:33:45.330 They typically consist of rings of metal or even other materials 00:33:45.330 --> 00:33:46.830 such as plastics. 00:33:46.830 --> 00:33:54.010 They can be in one piece or in several pieces clamped together using oil 00:33:54.010 --> 00:33:54.890 or fluid. 00:33:54.890 --> 00:33:58.369 Their function is to form a smooth bearing surface. 00:33:58.369 --> 00:34:01.590 MARTINEZ, SANDRA In which a shaft or an axle turned. 00:34:03.833 --> 00:34:07.250 MARTINEZ, SANDRA Keep in mind that this heading does not include graphite 00:34:07.250 --> 00:34:11.020 or other carbon bearings of heading 6815. 00:34:11.021 --> 00:34:14.868 This is because, note one to chapter 84 excludes machinery. 00:34:54.067 --> 00:34:57.928 MARTINEZ, SANDRA And This is why they're less prone to fatigue compared 00:34:57.928 --> 00:35:02.967 to ball or roller bearings whose rolling elements are, you know, 00:35:02.967 --> 00:35:06.100 in constant contact with the. 00:35:06.100 --> 00:35:08.212 MARTINEZ, SANDRA Whatever the component 00:35:08.212 --> 00:35:09.700 or part they're being used with. 00:36:21.767 --> 00:36:24.482 MARTINEZ, SANDRA Uh, so early in the presentation, I mentioned 00:36:24.482 --> 00:36:29.214 that we classify parts of machines that are classified 00:36:29.215 --> 00:36:35.900 in Chapter 84 according to Note 2 to section 16 and parts 00:36:35.900 --> 00:36:39.822 that are integral and identifiable to bearing housings and plane chef. 00:36:39.823 --> 00:36:44.600 Bearings are classified within subheading 8483.90 00:36:45.256 --> 00:36:50.333 One important exception is complete baller rare or roller bearings 00:36:50.333 --> 00:36:52.200 as they fall within heading. 00:36:52.200 --> 00:36:54.333 MARTINEZ, SANDRA 8482. 00:36:54.333 --> 00:36:55.591 MARTINEZ, SANDRA It makes sense. 00:36:55.591 --> 00:36:58.469 We just talked about this, those types of bearings fall 00:36:58.469 --> 00:37:01.317 within heading 8042, so. 00:37:01.984 --> 00:37:04.162 MARTINEZ, SANDRA And and this makes sense because it falls 00:37:04.162 --> 00:37:09.924 in line with note 2A to section 16 and also additional US rule 00:37:09.924 --> 00:37:11.098 of interpretation. 00:37:11.098 --> 00:37:16.476 One seat which States and relevance that are provisioned for parts are parts 00:37:16.476 --> 00:37:21.800 and accessories does not override a specific provision for such part 00:37:21.800 --> 00:37:22.834 or accessory. 00:37:27.300 --> 00:37:30.067 MARTINEZ, SANDRA OK, we'll help units. 00:37:30.067 --> 00:37:34.899 What are wheel hub units and how are wheel hub units 00:37:34.900 --> 00:37:37.534 that incorporate bearings classified? 00:37:41.254 --> 00:37:43.363 MARTINEZ, SANDRA Well, we'll hub units 00:37:43.364 --> 00:37:45.170 incorporating antifriction bearings 00:37:45.649 --> 00:37:49.698 are used in motor vehicles or industrial vehicles, 00:37:49.698 --> 00:37:55.738 and they're typically located between the brake drum and the axle. 00:37:55.738 --> 00:38:00.114 And for consideration of heading 8482, their purpose 00:38:00.115 --> 00:38:02.426 is to incorporate bearings. 00:38:03.388 --> 00:38:06.737 MARTINEZ, SANDRA And their primary function is to. 00:38:06.738 --> 00:38:10.840 MARTINEZ, SANDRA Reduce friction allowing for a smooth steering action. 00:38:14.715 --> 00:38:18.480 MARTINEZ, SANDRA Here we have an illustration of a wheel hub unit 00:38:18.480 --> 00:38:22.330 that incorporates bearings and you can see that the unit is connected 00:38:22.330 --> 00:38:25.640 to the hub carrier and in turn a CV joint. 00:38:25.640 --> 00:38:28.780 So if you're reading this drawing from left to right 00:38:28.780 --> 00:38:33.900 and following the large blue arrows, you can see that the hub has an outer 00:38:33.900 --> 00:38:37.790 and inner bearings that are incorporated within. 00:38:37.790 --> 00:38:41.880 MARTINEZ, SANDRA You know, overall, I really wanted to give you an idea 00:38:41.880 --> 00:38:45.670 of their connection and and and how they work and how they're in 00:38:45.670 --> 00:38:46.760 and where they're installed. 00:38:50.221 --> 00:38:53.540 MARTINEZ, SANDRA So for classification purposes, it's thought 00:38:53.540 --> 00:38:58.620 that wheel hub units, even with flanged outer and inner bearings, 00:38:58.620 --> 00:39:02.300 are simply bearings that are enhanced so that the bearings 00:39:02.300 --> 00:39:07.750 within can be mounted and connected to their appropriate components 00:39:07.750 --> 00:39:09.510 as a complete unit. 00:39:09.510 --> 00:39:12.110 Their primary function is to minimize friction. 00:39:13.016 --> 00:39:16.060 MARTINEZ, SANDRA Uh, we all have units of industrial vehicles 00:39:16.060 --> 00:39:17.570 and motor vehicles. 00:39:17.570 --> 00:39:24.350 Even generations 1/2 and some generation three are simply bearings 00:39:24.350 --> 00:39:25.340 that have been modified. 00:39:26.606 --> 00:39:30.310 MARTINEZ, SANDRA Uh, in ways that allow them to facilitate the mountings 00:39:30.310 --> 00:39:35.590 of the bearings, they tend to be a single unit, not bearings pressed 00:39:35.590 --> 00:39:36.890 into a frame. 00:39:38.900 --> 00:39:42.580 MARTINEZ, SANDRA Like the UM house bearings. 00:39:42.580 --> 00:39:47.960 Therefore, if the wheel hub units have no additional features beyond that 00:39:47.960 --> 00:39:52.370 of facilitating their ability to be mounted, they are classified 00:39:52.370 --> 00:39:58.750 within heading 8042, which is unlike a house bearing which we saw earlier, 00:39:58.750 --> 00:40:01.270 where you have again where you have. 00:40:01.270 --> 00:40:02.060 MARTINEZ, SANDRA Uh. 00:40:02.060 --> 00:40:05.370 A bearing or bearing with separate races that is pressed 00:40:05.370 --> 00:40:07.310 into his separate housing. 00:40:07.310 --> 00:40:08.870 The housing itself is not acting. 00:40:08.870 --> 00:40:13.160 MARTINEZ, SANDRA Umm, like the inner or outer race of the bearing? 00:40:17.250 --> 00:40:18.970 MARTINEZ, SANDRA While in case you're wondering 00:40:18.970 --> 00:40:24.380 what features would exclude a wheel hub unit from being classified 00:40:24.380 --> 00:40:30.370 within heading 8482, here we have a hub and I've heard this type 00:40:30.370 --> 00:40:37.510 being called a wheel bearing that features an ABS sensor connector 00:40:37.510 --> 00:40:41.170 and if you notice it also has splining or teeth that mesh 00:40:41.170 --> 00:40:46.070 with the teeth of a shot that's intended to transmit power. 00:40:46.070 --> 00:40:47.990 The Splining is particularly found with. 00:40:47.990 --> 00:40:52.340 MARTINEZ, SANDRA We'll have units that are for driven wheels. 00:40:52.340 --> 00:40:57.310 It's what allows the splined axle to marry up with the wheel hub unit. 00:40:58.302 --> 00:40:59.947 MARTINEZ, SANDRA So these are features 00:40:59.948 --> 00:41:02.270 that give the hub unit functionality 00:41:02.270 --> 00:41:05.060 beyond that of just minimizing free friction. 00:41:05.060 --> 00:41:09.450 It's what makes it a part of like the breaking system or the steering system. 00:41:09.450 --> 00:41:15.010 And heading 8482 simply provides for anti friction bearings. 00:41:15.010 --> 00:41:19.010 So this type of hub would be excluded from 8482. 00:41:24.393 --> 00:41:27.189 MARTINEZ, SANDRA So what about a wheel hub unit like this one? 00:41:28.260 --> 00:41:32.930 It's for a motor vehicle and you can see that the ABS sensor is in present. 00:41:34.367 --> 00:41:37.160 MARTINEZ, SANDRA Well, it too would be excluded 00:41:37.160 --> 00:41:42.150 because as I mentioned, the teeth right in the center are features 00:41:42.150 --> 00:41:45.090 that relate to the transmission of power. 00:41:45.090 --> 00:41:50.720 And we know that such functionality doesn't fall in the scope of 8042. 00:41:50.720 --> 00:41:57.320 MARTINEZ, SANDRA But does it fall outside of heading 8483? 00:41:57.320 --> 00:42:01.800 You might be thinking about this because you know it does transmit power. 00:42:03.100 --> 00:42:06.830 MARTINEZ, SANDRA So doesn't that meet the terms of heading 8483? 00:42:09.433 --> 00:42:11.280 MARTINEZ, SANDRA Well, it doesn't. 00:42:11.280 --> 00:42:12.780 It would be excluded. 00:42:12.780 --> 00:42:16.200 It's thought that the splining makes it part of the, you know, 00:42:16.200 --> 00:42:22.340 the steering or the driving system, whether it's for an industrial vehicle 00:42:22.340 --> 00:42:28.500 or motor vehicle and in particular for a motor vehicle, it's very clear why, 00:42:28.500 --> 00:42:31.540 because if you recall DRI one, it says that we have 00:42:31.540 --> 00:42:35.680 to consider any relative section or chapter nodes. 00:42:35.680 --> 00:42:38.510 And in this case we consider note 1L to section. 00:42:38.510 --> 00:42:44.540 MARTINEZ, SANDRA 16 which excludes articles of section 17. 00:42:44.540 --> 00:42:48.700 Motor vehicles are articles of section 17. 00:42:48.700 --> 00:42:54.310 MARTINEZ, SANDRA Also, we have explanatory note B to heading 8483 00:42:54.310 --> 00:42:55.780 which gives us some guidance. 00:42:56.770 --> 00:43:02.400 MARTINEZ, SANDRA And it says that transmission equipment that is described 00:43:02.400 --> 00:43:04.067 by the heading. 00:43:04.067 --> 00:43:07.930 MARTINEZ, SANDRA Is excluded from this heading, UM if it's designed 00:43:07.930 --> 00:43:13.260 for solely or principally with vehicles of section 17. 00:43:13.260 --> 00:43:17.920 MARTINEZ, SANDRA Uh, of course, this rule does not apply to internal parts 00:43:17.920 --> 00:43:22.380 of vehicle engines, but we know that we'll hub units are not used 00:43:22.380 --> 00:43:24.810 in engines of a motor vehicle. 00:43:24.810 --> 00:43:28.330 As we mentioned earlier, there used like in the suspension section 00:43:28.330 --> 00:43:30.090 of a motor vehicle. 00:43:30.090 --> 00:43:36.090 Therefore, if the wheel hub units are used with motor vehicles 00:43:36.090 --> 00:43:41.200 and they have functionality beyond that of heading 8482, 00:43:41.200 --> 00:43:43.090 they would be classified as a part of it. 00:43:43.090 --> 00:43:44.910 MARTINEZ, SANDRA Of that of a motor vehicle. 00:43:50.790 --> 00:43:54.020 MARTINEZ, SANDRA Here's a question I see that comes up often 00:43:54.020 --> 00:43:56.300 with wheel hub units. 00:43:56.300 --> 00:44:01.920 What about wheel hub units which incorporate a bearings that are designed 00:44:01.920 --> 00:44:06.640 to be used in a specific motor vehicle or a specific machine? 00:44:06.640 --> 00:44:11.340 Aren't those specifically made units classified within heading 8482? 00:44:14.278 --> 00:44:21.980 MARTINEZ, SANDRA Well, ruling 960049 gives us some guidance in this ruling. 00:44:21.980 --> 00:44:27.990 We have a a discussion, a wheel hub unit that's used on a Lincoln Town car. 00:44:27.990 --> 00:44:33.770 The ruling explains that while the wheel hub may be designed specifically 00:44:33.770 --> 00:44:38.770 for a Lincoln town car, it's not legally relevant because many ball 00:44:38.770 --> 00:44:43.290 or rolling bearing types are manufactured to specific engineering. 00:44:43.290 --> 00:44:46.660 MARTINEZ, SANDRA And design criteria and their perches 00:44:46.660 --> 00:44:49.740 with a particular application in mind. 00:44:49.740 --> 00:44:54.870 So as the wheel hub unit had no additional features, it was classified 00:44:54.870 --> 00:45:00.780 within heading 8482, even though it had a particular application. 00:45:00.780 --> 00:45:04.320 And this makes sense because if the bearing doesn't have a precise fid 00:45:04.320 --> 00:45:05.200 or connection. 00:45:05.200 --> 00:45:08.160 MARTINEZ, SANDRA It won't achieve what's intended to do, 00:45:08.160 --> 00:45:10.250 which is to minimize friction. 00:45:10.250 --> 00:45:15.170 It just wouldn't be able to serve its purpose, so you know, 00:45:15.170 --> 00:45:19.790 and it's just known that bearings tend to be manufactured 00:45:19.790 --> 00:45:22.800 for specific applications most of the time. 00:45:22.800 --> 00:45:25.720 I mean, there are some that can fit more than one application, 00:45:25.720 --> 00:45:30.400 but nevertheless it doesn't have any effect on classification. 00:45:30.400 --> 00:45:36.690 MARTINEZ, SANDRA OK, so we're coming to the end of the presentation, 00:45:36.690 --> 00:45:39.760 but I didn't wanna end without mentioning the open case 00:45:39.760 --> 00:45:42.690 for tapered roller bearings. 00:45:42.690 --> 00:45:46.720 It's a 570601. 00:45:46.720 --> 00:45:50.850 The scope of this case concerns tapered roller bearings and parts 00:45:50.850 --> 00:45:53.080 of tapered roller bearings from China. 00:45:53.080 --> 00:45:55.410 From I'm sorry from China, the subheading lists. 00:45:55.410 --> 00:45:58.010 MARTINEZ, SANDRA The barriers. 00:45:59.167 --> 00:46:02.170 MARTINEZ, SANDRA Scopes that may fall under the scope of the case, 00:46:02.170 --> 00:46:06.110 but it's the scope language that you wanna pay particular attention to. 00:46:06.110 --> 00:46:09.580 It's that information that's used to determine whether a bearing falls 00:46:09.580 --> 00:46:12.370 within the scope of the anti dumping case or not. 00:46:17.136 --> 00:46:20.490 MARTINEZ, SANDRA So here's the summary of what we discussed today. 00:46:20.490 --> 00:46:24.960 Heading 8482 provides for ball or roller type of bearings 00:46:24.960 --> 00:46:28.550 that are not housed or installed in a frame. 00:46:28.550 --> 00:46:34.030 Heading 8483 provides for house bearings bearing housings 00:46:34.030 --> 00:46:35.680 and plane shot bearings. 00:46:36.740 --> 00:46:40.380 MARTINEZ, SANDRA And #3 wheel hub units are classified 00:46:40.380 --> 00:46:46.070 within heading 8042, provided they have characteristics that fall 00:46:46.070 --> 00:46:47.130 within the scope of the heading. 00:46:49.364 --> 00:46:50.910 MARTINEZ, SANDRA Of course, if you would like 00:46:50.910 --> 00:46:55.630 to hear this presentation again, I've included the link for the webinar 00:46:55.630 --> 00:47:00.190 at the bottom of the slide and I think it was included in the chat box. 00:47:00.190 --> 00:47:03.030 It will take some time before it gets posted. 00:47:03.030 --> 00:47:06.550 It needs to go through its checks so it may take, I don't know, 00:47:06.550 --> 00:47:10.680 a few weeks or so, but before you know it, it will be posted. 00:47:14.055 --> 00:47:15.430 MARTINEZ, SANDRA OK. 00:47:15.430 --> 00:47:18.320 Uh, we reached the end of the presentation. 00:47:18.320 --> 00:47:20.970 Does anyone have any questions? 00:47:20.970 --> 00:47:24.230 If you do, you can simply type them in the chat box. 00:47:33.570 --> 00:47:37.610 MARTINEZ, SANDRA OK, I see where would magnetic bearings be classified? 00:47:37.610 --> 00:47:40.500 MARTINEZ, SANDRA In China, certain magnetic bearings 00:47:40.500 --> 00:47:44.300 are classified 8483 thirty. 00:47:44.300 --> 00:47:47.240 MARTINEZ, SANDRA Umm, it really depends. 00:47:47.240 --> 00:47:50.830 I mean, is it housed or are they? 00:47:50.830 --> 00:47:55.460 Are they roller type or are they housed or plane shaft? 00:47:55.460 --> 00:47:59.570 It's kind of general, I don't I'm not really come across too many 00:47:59.570 --> 00:48:01.350 of those types of bearings. 00:48:08.436 --> 00:48:10.220 MARTINEZ, SANDRA Should let me see here if I can. 00:48:16.340 --> 00:48:18.060 MARTINEZ, SANDRA Their housed with magnets. 00:48:19.651 --> 00:48:20.950 MARTINEZ, SANDRA Hum. 00:48:22.115 --> 00:48:22.755 MARTINEZ, SANDRA Umm. 00:48:26.316 --> 00:48:28.410 MARTINEZ, SANDRA You know I can't picture what those look like. 00:48:28.410 --> 00:48:33.390 I mean, I think I think I understand, but I'm, I'm I'm not quite sure. 00:48:33.390 --> 00:48:35.410 Would you mind sending me an email with that? 00:48:35.410 --> 00:48:39.770 And then I'll take a look and see if you know, that's something that would go. 00:48:39.770 --> 00:48:42.130 MARTINEZ, SANDRA They resemble roller bearings. 00:48:42.130 --> 00:48:44.200 MARTINEZ, SANDRA That are housed. 00:48:45.500 --> 00:48:47.800 MARTINEZ, SANDRA Maybe I need to take a look at it and see 00:48:47.800 --> 00:48:50.610 how the the magnets function. 00:48:50.610 --> 00:48:55.190 I don't wanna give you any incorrect direction or anything like that. 00:48:55.190 --> 00:48:58.440 Just send me an email and I will definitely take a look at that. 00:49:02.633 --> 00:49:03.150 MARTINEZ, SANDRA OK. 00:49:03.150 --> 00:49:05.660 Does anyone else have any questions? 00:49:05.660 --> 00:49:06.410 I don't see anything. 00:49:11.480 --> 00:49:14.199 MARTINEZ, SANDRA OK, well, if you have any questions 00:49:14.200 --> 00:49:16.884 that you think of later or you prefer to address offline, 00:49:16.885 --> 00:49:19.600 here's my contact information emails. 00:49:19.600 --> 00:49:23.760 Probably the quickest way to reach me since there are days I do telework. 00:49:24.920 --> 00:49:27.580 But before I conclude this webinar, I wanna say thank you 00:49:27.580 --> 00:49:33.150 to the NCSD webmasters I worked with Simon a Fong and Amy. 00:49:33.150 --> 00:49:37.100 Thanks to y'all, we were able to complete the webinar today 00:49:37.100 --> 00:49:41.180 and of course, thank you to everyone for taking time out of your day 00:49:41.180 --> 00:49:41.770 to listen in. 00:49:41.770 --> 00:49:44.860 MARTINEZ, SANDRA Thanks and have a great day everyone.
