30217JR Tapered Roller Bearing, 85 mm Inner Diameter x 150 mm Outer Diameter x 30.5 mm Width

The 30217JR is a metric tapered roller bearing from the 302 series, featuring an 85 mm bore diameter. Tapered roller bearings use conical rolling elements to handle combined radial and axial loads in a single direction.

This bearing type is commonly used in automotive wheel hubs, gearboxes, industrial transmissions, and heavy machinery where robust load capacity and precise shaft positioning are required. The tapered design allows for adjustment of bearing clearance during installation.
