Angular contact ball bearings are named because the contact surface between the ball and the inner and outer rings of an angular contact ball bearing is in the form of an included angle.The lock of this kind of bearing is on the outer ring, and generally the inner and outer rings cannot be separated.

Single row angular contact ball bearings can only withstand axial loads acting in one direction. When subjected to purely radial loads, these bearings must be installed in pairs.
Double row angular contact ball bearings are equivalent to a pair of single row angular contact ball bearings mounted back to back, but takes up relatively less axial space.  The type of this bearing can withstand axial and radial loads in two directions, and can limit the axial displacement in the two raceway directions of the shaft and the housing. Its contact angle is 30°.
