30216JR Single Row Tapered Roller Bearing

The 30216JR is a metric tapered roller bearing with an 80 mm bore diameter from the 302 series. Tapered roller bearings use conical rolling elements to handle combined radial and axial loads, with load capacity proportional to contact angle.

This bearing type is commonly used in automotive wheel hubs, gearboxes, transmissions, and industrial equipment such as conveyors and machine tool spindles where both radial and thrust loads are present. Single row tapered roller bearings require proper adjustment and are typically mounted in pairs for optimal performance.
