Angular contact ball bearings | SKF

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 coined load is transmitted from one raceway to another, and a line perpendicular to the bearing axis ( fig. 1 ).
