8483.20.80.80 - Incorporating roller bearings

This HTS category, 8483.20.80.80, specifically covers housed bearings that incorporate roller bearings. These are mechanical components designed to reduce friction in rotating shafts. The "housed" aspect signifies that the bearing assembly is enclosed within an outer casing or housing, which can be designed for mounting to machinery. This category encompasses a broad range of such housed roller bearings used in various industrial and mechanical applications.

Crucially, this category is distinguished from its sibling, 8483.20.80.40, by the type of rolling element used within the bearing. While 8483.20.80.40 is reserved for housed bearings incorporating *ball* bearings, this current category is exclusively for those that utilize *roller* bearings. The distinction lies in the shape of the rolling elements, which impacts their load-carrying capacity and operational characteristics.

As this is a leaf node, there are no further subcategories under 8483.20.80.80. Therefore, the classification relies on accurately identifying the presence of roller bearings within a housed bearing assembly and ensuring it doesn't fall under the specific ball-bearing classification. The focus for classification within this category is on the specific design of the roller bearing and its housing, as well as its intended function in power transmission and machinery.
