The thrust angular contact thrust ball bearing is a detachable-bearing, when the contact angle is 90, bearing can be installed separately, and it can only bear axial loads. Low speed limit. Ball and centrifugal force crowd outer raceway, easily scratch, not suitable for high-speed operation. In contrast to conventional thrust ball bearings, angular contact thrust ball bearings can accommodate radial loads in addition to axial loads and are able to operate at high speeds.

One kind of thrust angular contact ball bearings is Double direction thrust angular contact ball bearing, they have high accuracy and are especially designed for spindles of machine tools. They are able to carry axial loads in both directions. By comparison with thrust ball bearings, their ball diameter is smaller and number is more. Their contact angle is 60 degree. Therefore, the influence of centrifugal force is reduced, they are well suitable to high speed application and their stiffness is higher.

And at last we know thrust angular contact ball bearings mainly used to machine spindle, vertical lathe rotary table, automobile steering mechanism,and so on.
