I. Product Description - Angular Contact Ball Bearing

Angular Contact Ball Bearings have raceways in the inner and outer rings that are displaced with respect to each other in the direction of the bearing axis. The axial load carrying capacity of angular contact Ball bearings increases with increasing contact angle. The contact angle α 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 load is transmitted from one raceway to another, and a line perpendicular to the bearing axis.
