8482.80.00.20 - Combined ball and spherical roller bearings

This HTS category, 8482.80.00.20, specifically covers combined bearings that integrate both ball and spherical roller bearing elements. These bearings are designed to simultaneously accommodate axial and radial loads, leveraging the distinct load-carrying capabilities of both bearing types within a single assembly. Examples include bearings where a set of balls handles radial loads and a set of spherical rollers manages combined radial and axial loads, or vice versa.

It is crucial to distinguish this classification from its siblings. Category 8482.80.00.40 encompasses combined bearings featuring balls and needle rollers, which have a different roller geometry and load distribution profile. Similarly, 8482.80.00.60 covers combined bearings with balls and other cylindrical rollers, where the rollers are straight and typically handle primarily radial loads. Category 8482.80.00.80 serves as a residual category for all other combined bearings not otherwise specified.

As a leaf node within the HTS structure, this classification does not have further subdivisions. Therefore, the primary classification criterion remains the precise combination of ball and spherical roller bearing elements within a single unit. Classification under this code relies on the physical construction and intended function of the bearing assembly to manage loads that necessitate the combined attributes of both bearing types.
