For angular contact ball bearing, the standard contact angle is 15degree, 25degree and 40degree respectively confifureing with code "C", "AC", "B".
The more contact angle is, the larger axial load bearing capacity is!
The angular contact ball bearing creates axial thrust load when being forced by radial load, thus it is configureed face to face or back to back!
