The raceways of the single row angular contact ball bearings are in such position, that the connecting line of their contact points with the balls form an acute angle with the perpendicular line to the bearing axis, or contact angle.

Bearings of design B have a contact angle α = 40° and have a high number of balls with good conformability which ensures their high load rating.

They can carry radial loads acting simultaneously with high axial forces in one direction. Bearings are arranged in pairs so that axial guiding in both direction can be achieved.

Single row angular contact ball bearings of the design AA with a contact angle of α = 26° are used in applications with a higher axial load.

Bearings of the design B and AA are non-separable, although both rings have only one rib.
