30218JR Tapered Roller Bearing, 90 mm Inner Diameter x 160 mm Outer Diameter x 32.5 mm Width

The 30218JR is a metric tapered roller bearing conforming to ISO 355 standards, with a 90 mm bore diameter from the 302 series. Tapered roller bearings use conical raceways and tapered rollers to handle combined radial and axial loads efficiently.

Tapered roller bearings are commonly used in automotive wheel hubs, gearboxes, differential assemblies, and industrial machinery where heavy radial and thrust loads occur simultaneously. Their design allows for adjustment of bearing clearance during installation.
