8482.30.00.40 - Single row

This HTS category, 8482.30.00.40, specifically encompasses single-row spherical roller bearings. These bearings are characterized by two rows of barrel-shaped rollers, with a common spherical outer ring raceway and two inner ring raceways. They are designed to accommodate heavy radial loads and moderate axial loads in both directions, making them suitable for demanding applications where misalignment or shaft deflection is a concern. Their construction allows for self-aligning capabilities within the bearing unit.

This classification distinguishes itself from its sibling category, 8482.30.00.80 "Other," which covers spherical roller bearings that do not fit the "single row" criteria. Therefore, the primary differentiating factor is the number of roller rows and the specific design configurations that define a single-row spherical roller bearing.

As a leaf node, this category does not have further subcategories. Classification within 8482.30.00.40 is determined by the precise physical characteristics of spherical roller bearings, namely their single-row configuration and their spherical roller design, which allows them to handle misalignment and significant loads. Importers should ensure that the bearings they are declaring precisely match this description to ensure correct customs clearance.
