8483.30.80.90 - Other

This HTS category, 8483.30.80.90, covers "Other" plain shaft bearings without housings. These are critical components designed to support rotating shafts and reduce friction between moving parts. They function by providing a smooth surface upon which a shaft can turn, often with the aid of a lubricant. Examples include bushings, sleeve bearings, and journal bearings made from various materials such as bronze, babbitt metal, or plastics, provided they do not incorporate a separate housing.

This classification is distinct from its sibling category, 8483.30.80.70, which specifically enumerates "Spherical" plain shaft bearings. While both fall under the broader umbrella of plain shaft bearings without housings, the "Spherical" category is reserved for bearings designed with a spherical raceway. Category 8483.30.80.90, conversely, encompasses all other configurations of plain shaft bearings that lack integrated housings and are not of the spherical type. This includes cylindrical, flanged, or other specialized shapes of plain bearings.

As a leaf node, this category has no further subcategories. Therefore, the focus for classification within 8483.30.80.90 lies in definitively identifying plain shaft bearings that lack a housing and are not spherical. Classification hinges on the absence of a separate housing unit and the non-spherical geometry of the bearing surface.
