30314JR Tapered Roller Bearing, 70 mm Inner Diameter x 150 mm Outer Diameter x 38 mm Width

The 30314JR is a metric tapered roller bearing conforming to ISO 355 standards, featuring a 70 mm bore diameter. Tapered roller bearings use conical rolling elements to handle combined radial and axial loads through a contact angle design.

This bearing type is commonly used in automotive wheel hubs, gearboxes, differential assemblies, and industrial machinery where simultaneous radial and thrust load capacity is required. The tapered geometry allows for precise adjustment of bearing clearance during installation.
