7322B 110x240x50 Bearing
Single Row Angular Contact Ball Bearings
The 7322B bearing is designed with a unique angular contact configuration, where the raceways of both the inner and outer rings are displaced relative to each other along the bearing axis. This design allows the bearing to support axial loads while also handling moderate radial loads. The contact angle, typically around 40 degrees for the 7322B, enables the bearing to achieve higher axial load capacity, making it ideal for applications where combined loads are present.
