387AS/382A
The 387AS/382A is a tapered roller bearing set consisting of a cone (inner ring with rollers and cage) and cup (outer ring). This single row design uses tapered raceways to accommodate combined radial and axial loads, with load capacity increasing with the contact angle.
Tapered roller bearing sets are widely used in automotive axles, transmissions, wheel hubs, and industrial gearboxes where both radial and thrust loads are present. The separable design allows for independent mounting and precise adjustment of internal clearance during installation.
