High speed angular contact ball bearing(71911C/71911AC)

The contact angle of the ball bearing typically varies from 15 to 40 degrees and is measured in relative proportion to the line running perpendicular to the bearing axis. Angular contact bearings are unidirectional thrust ball bearings that can bear heavy thrust loads and moderate radial loads. They are designed to sustain higher axial loads in one direction along with radial loads where a contact angle is formed between the races in the radial plane and the line joining the points of contact of the balls when the bearing is in use. This permits the bearing to transmit the load from one raceway to another in a perpendicular line to that of the bearing`s axis. As externally applied loads are transmitted from one ring to the other along a specific angle, the inner and outer race gain the same angle of contacts. The higher the axial load, the lower the radial load supported.
