HS Code 8482 covers ball or roller bearings. The classification includes detailed subcategories for ball bearings (8482.10), tapered roller bearings (8482.20), spherical roller bearings (8482.30), needle roller bearings (8482.40), other cylindrical roller bearings (8482.50), other bearings including combined types (8482.80), and parts (8482.91-8482.99). This precision mechanical components category includes engineered elements that enable low-friction rotational or linear movement. Products range from miniature bearings for electronic devices to massive industrial bearings for heavy machinery. Manufacturing involves high-precision machining, grinding, heat treatment, and assembly under controlled conditions. Technical specifications focus on load ratings, rotational speed limits, dimensional precision, and durability under operational conditions. Applications span virtually all machinery sectors, from household appliances to aerospace systems. This division represents critical enabling components that minimize friction and wear in moving mechanical systems, enhancing efficiency, precision, and reliability in applications where parts must rotate or move relative to each other under load.
