33021J Tapered Roller Metric Type

The 33021J is a tapered roller bearing designed to metric ISO 355 standards with a 105 mm bore diameter. Tapered roller bearings use conical raceways and tapered rollers to handle combined radial and axial loads, with load capacity increasing proportionally to bearing size.

This bearing type is commonly used in heavy industrial applications including gearboxes, wheel hubs, axle assemblies, and machine tool spindles where robust performance under combined loading conditions is required. The separable design allows for independent mounting of inner and outer ring assemblies.
