30221JR Tapered Roller Bearing, 105 mm Inner Diameter x 190 mm Outer Diameter x 39 mm Width

The 30221JR is a metric tapered roller bearing from the 302 series with a 105 mm bore diameter, 190 mm outer diameter, and 39 mm width. Tapered roller bearings use conical raceways and tapered rollers to handle combined radial and axial loads in a single direction.

This bearing type is commonly used in heavy machinery, automotive wheel hubs, gearboxes, and industrial equipment where robust load capacity and reliable performance under combined loading conditions are required. The tapered design allows for precise adjustment of bearing clearance during installation.
