The 3980/3920 is a tapered roller bearing set consisting of a cone (inner ring with rollers and cage) and cup (outer ring). Tapered roller bearings use conical rolling elements to handle combined radial and thrust loads, with load capacity increasing with the contact angle.
Commonly used in automotive wheel hubs, transmissions, differentials, and industrial gearboxes where both radial and axial forces are present. The separable design allows for precision adjustment of bearing clearance during installation and accommodation of thermal expansion in shaft assemblies.
