32309JR Tapered Roller Bearing, 45 mm Inner Diameter x 100 mm Outer Diameter x 38.25 mm Width

The 32309JR is a metric tapered roller bearing conforming to ISO 355 standards, featuring a 45 mm bore diameter, 100 mm outer diameter, and 38.25 mm width. Tapered roller bearings use conical raceways and tapered rollers to handle combined radial and axial loads efficiently.

This bearing type is commonly used in automotive wheel hubs, gearboxes, differential assemblies, and industrial machinery requiring high load capacity and precise shaft positioning. The tapered geometry allows for adjustment of bearing clearance during installation.
