8483.30.80.20 - Ball or roller bearing type

This HTS category, 8483.30.80.20, specifically covers ball or roller bearing types within the broader classification of bearing housings and plain shaft bearings. These are distinct from plain shaft bearings which rely on sliding friction, and instead utilize rolling elements (balls or rollers) to reduce friction and enable rotation or linear movement. This category encompasses the complete assembled bearing unit, where the rolling elements are housed within races.

While the sibling category 8483.30.80.40 also falls under "Other" bearing housings, the key distinction for this subcategory lies in its reliance on rolling element technology for friction reduction. This includes various types of ball bearings and roller bearings, such as deep groove ball bearings, angular contact ball bearings, cylindrical roller bearings, spherical roller bearings, and tapered roller bearings, among others, as long as they are presented as complete units of bearing housings. The focus is on the presence and function of the rolling elements as the primary means of support and low-friction movement.

As this is a leaf node, there are no further subcategories. Therefore, classification within 8483.30.80.20 is determined by identifying a complete bearing unit that incorporates ball or roller elements for its primary function. This encompasses a wide range of standard and specialized rolling element bearings used across various industries for rotational or linear motion applications where reduced friction and precise movement are critical.
