Angular contact ball bearings can accommodate both radial and axial loads simultaneously and are capable of operating at high speeds. The axial load-carrying capacity increases as the contact angle increases. The contact angle is defined as the angle between the line connecting the contact points of the ball and the raceways (in a radial plane) and a line perpendicular to the bearing axis. High-precision, high-speed bearings typically feature a contact angle of 15 degrees. Under the influence of axial force, the contact angle increases.
Angular contact ball bearings feature raceways on both the inner and outer rings, which can undergo relative displacement along the bearing axis. These bearings are particularly well-suited for handling combined loads-that is, loads acting simultaneously in both radial and axial directions. The axial load-carrying capacity of angular contact ball bearings increases with the contact angle (α). The contact angle is defined as the angle between the line connecting the contact points of the ball and the raceways (in a radial plane) and a line perpendicular to the bearing axis.
Angular contact ball bearings are classified into 13 types: angular contact ball bearings with α=15° (Type 70000C); α=25° (Type 70000AC); α=40° (Type 70000B); back-to-back paired angular contact ball bearings [Type 70000C(AC, B)/DB]; face-to-face paired angular contact ball bearings [Type 70000C(AC, B)/DF]; tandem paired angular contact ball bearings [Type 70000C(AC, B)/DT]; double-row angular contact ball bearings with filling slots (Type 00000); double-row angular contact ball bearings without filling slots (Type 00000A); double-row angular contact ball bearings without filling slots and with a dust shield on one side (Type 00000A-Z); double-row angular contact ball bearings without filling slots and with dust shields on both sides (Type 00000A-2Z); double-row angular contact ball bearings without filling slots and with a seal on one side (Type 00000ARS); double-row angular contact ball bearings without filling slots and with seals on both sides (Type 00000A-2RS); and four-point contact ball bearings (Type QJ0000).
