7202B 15x35x11 Bearing
Single Row Angular Contact Ball Bearings
The 7202B bearing is a single row angular contact ball bearing, which means it is designed to handle both radial and axial loads. Unlike traditional radial ball bearings, angular contact ball bearings are built to support loads that are applied at an angle. This is achieved through the bearing’s design, which features inner and outer ring raceways that are displaced relative to each other in the direction of the bearing axis. This unique design allows the 7202B bearing to support combined loads—simultaneously handling forces in both the radial and axial directions.
