The 387A/382A is a single row tapered roller bearing set consisting of a cone (inner ring with rollers and cage) and cup (outer ring). This inch-series design provides high radial and thrust load capacity through its tapered raceway geometry.
Tapered roller bearing sets are commonly used in automotive wheel hubs, truck axles, gearboxes, and industrial machinery where combined radial and axial loads must be supported. The separable design allows for precision adjustment of bearing clearance during installation.
