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.

Angular Contact Ball Bearings are classified into three sub-categories:

1. Single Row

They have three different contact angle classifications:

C15 degrees
AC25 degrees

2. Double Row

They have two different contact angle classifications:
