8482.30.00 - Spherical roller bearings

This HTS category, 8482.30.00, specifically covers spherical roller bearings. These bearings are characterized by their two rows of rollers that can accommodate significant radial loads and moderate axial loads in either direction. Their outer ring has a common spherical raceway, allowing them to compensate for misalignment between the shaft and housing.

Unlike other categories within 8482, spherical roller bearings are distinct from ball bearings (8482.10), which use balls for rolling elements and are typically suited for higher speeds but lower load capacities. They also differ from tapered roller bearings (8482.20.00), which are designed to handle both radial and axial loads but are not capable of accommodating misalignment. Furthermore, they are distinguished from needle roller bearings (8482.40.00.00) and cylindrical roller bearings (8482.50.00.00), which have different roller geometries and load-handling characteristics.

Within the 8482.30.00 classification, further subdivisions exist to refine the classification. The subcategories differentiate based on the bearing's configuration: "Single row" (8482.30.00.40) refers to spherical roller bearings with a single set of rollers, while "Other" (8482.30.00.80) encompasses variations such as double-row spherical roller bearings or assemblies. This distinction aids in precise identification and adherence to customs regulations.
