32004JR Tapered Roller Bearing, 20 mm Inner Diameter x 42 mm Outer Diameter x 15 mm Width

The 32004JR is a metric tapered roller bearing with a 20 mm bore diameter from the 320 series. Tapered roller bearings use conical raceways and tapered rollers to handle combined radial and axial loads in a single direction.

This bearing type is commonly used in automotive wheel hubs, gearboxes, differentials, and industrial machinery requiring high radial and thrust load capacity. The tapered geometry allows for adjustment of bearing clearance during installation.
