8483.20.40.80 - Incorporating roller bearings

This HTS category, 8483.20.40.80, specifically covers housed units designed to incorporate roller bearings. These units are pre-assembled assemblies that provide a convenient and protected housing for roller bearings, simplifying installation and enhancing protection against contaminants. Examples include pillow blocks, flanged units, take-up units, and hanger units, all featuring integrated roller bearings. The purpose of these housed units is to facilitate smooth rotational movement by supporting and guiding shafts, commonly found in various industrial machinery, conveyor systems, and power transmission applications.

This classification is distinct from its sibling category, 8483.20.40.40, which covers housed units incorporating ball bearings. The primary differentiator lies in the type of rolling element used within the housing: roller bearings for this category versus ball bearings for its sibling. This distinction is critical for accurate classification, as the operational characteristics, load capacities, and typical applications of roller bearings differ significantly from those of ball bearings. Therefore, the presence and type of rolling element (roller vs. ball) are the key criteria for distinguishing between these two closely related categories.

As this HTS code represents a leaf node, there are no further subcategories within 8483.20.40.80. Classification at this level is determined by the combination of a housed unit and the inclusion of roller bearings. The specific design features, such as whether the unit is a flange, take-up, cartridge, or hanger type, do not create separate subheadings at this granularity. Instead, all such roller-bearing-incorporating housed units fall under this single HTS code.
