The SKF Angular contact ball bearing has 20mm inner bore and 25mm outer ring raceways that are displaced relative to each other in the direction of the bearing axis. This bearing is designed to accommodate combined loads, i.e. Simultaneously acting radial and axial loads.
The axial load carrying capacity of angular contact ball bearings increases as the contact angle increases. The contact angle is defined as the angle between the line joining the points of contact of the ball and the raceways in the radial plane, along which the combined load is transmitted from one raceway to another, and a line perpendicular to the bearing axis.
