Angular contact ball bearings have inner and outer ring raceways displaced along the bearing axis. This design accommodates combined loads, including radial and axial loads.
As the contact angle increases, the axial load-carrying capacity of angular contact ball bearings also increases. The contact angle refers to the angle between the contact points of the ball and raceways. This angle determines how the combined load transfers from one raceway to another, relative to a line perpendicular to the bearing axis.
