See specification of bearings

The raceway of both inner and outer rings of Angular Contact Ball Bearings is designed to maintain a specific contact angle between the balls and raceways, in the radial plane.

Standard cage materials for this type are pressed steel, high strength brass or synthetic resin. In comparison to a Deep Groove Ball Bearing, Angular Contact type generally carries more number of rolling elements (balls), and is capable of sustaining radial, axial or composite loads.
