8483.30.80.70 - Spherical 🖩

This HTS classification, 8483.30.80.70, specifically designates "Spherical" plain shaft bearings that are without housing. These bearings are designed to reduce friction between moving parts by allowing rotational or sliding movement between surfaces, with the key characteristic being their spherical form which can accommodate misalignment. They are distinct from other types of plain shaft bearings by their inherent spherical geometry.

This specific subheading distinguishes itself from its sibling, 8483.30.80.90 "Other," which would cover plain shaft bearings without housing that are not spherical. The spherical design often implies a self-aligning capability, allowing for variations in shaft alignment that might not be manageable with non-spherical plain bearings. The absence of a housing means these bearings are typically integrated directly into a larger assembly or system.

As a leaf node, 8483.30.80.70 does not have further subdivisions. Therefore, the classification relies heavily on the precise identification of the "spherical" characteristic. Examples within this category would include spherical plain bearings used in automotive suspension components, industrial machinery requiring self-aligning capabilities, or even specialized applications in aerospace where flexibility and compact design are paramount. The focus for classification here is the inherent spherical nature of the bearing element itself when it is not encased in a separate housing.
