Angular contact bearings were created so that a contact angle in between the races and also the balls is formed once the bearing is in use. The main design feature of angular contact bearing is usually that one, or both of the ring races have one shoulder relieved, or higher compared to other. To ensure that angular contact bearings to operate properly, they ought to be assembled which has a thrust load. This loading (or preload) results in a line of contact (or contact angle) in between the inner race, the ball and also the outer race. The preload could be constructed into the bearing or created while the bearing is placed into an assembly. The contact angle differs from 15 degree to 40 degree and it is calculated relative to a line running perpendicular to the bearing axis. Angular contact bearings are unidirectional thrust bearings which could withstand heavy thrust loads and reasonable radial loads.
