8482.91.00.70 - Spherical rollers

This HTS category, 8482.91.00.70, specifically encompasses spherical rollers. These are cylindrical rollers with rounded ends designed for use in bearings. Their characteristic shape allows for a specific type of load distribution and movement within the bearing assembly.

It is crucial to distinguish spherical rollers from their sibling categories. Unlike the "Balls" which are perfectly round, or "Needles" which are very long and slender rollers, spherical rollers possess a distinctly rounded termination to their cylindrical form. Furthermore, they are differentiated from "Tapered rollers," which have a conical shape, and "Other cylindrical rollers," which typically have flat, unchamfered ends. The defining characteristic here is the spherical or rounded profile at the ends of the roller.

As this is a leaf node in the HTS structure, there are no further subcategories under 8482.91.00.70. Therefore, classification within this code relies on the precise identification of the roller's spherical end geometry and its intended use as a component within a ball or roller bearing assembly, as defined by the broader scope of Chapter 84.
