Angular contact ball bearings have inner and outer ring raceways that are displaced relative to each other in the direction of the bearing axis. This means that these bearings are 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.
Incorporating a large number of balls to give it a relatively high load carrying capacity, these bearings can accommodate axial loads in one direction only, are typically adjusted against a second bearing...
With a design corresponding to two single row bearings arranged back-to-back, but where two single bearings take up too much axial space, they can accommodate radial and axial loads in either direction and...
Designed to support axial loads in both directions and have a high load carrying capacity, these bearings can support a limited radial load for a given axial load, use less axial space than double row...
