Angular Contact Ball Bearings (AngularContactBallBearings) can simultaneously accept radial load and axial load. Can work at higher speeds. The larger the contact angle, the higher the axial load capacity. The contact angle is the angle between the line of contact points between the ball and the raceway in the radial plane and the vertical line of the bearing axis. High-precision and high-speed bearings usually take a contact angle of 15 degrees. Under the action of axial force, the contact angle will increase.

  Angular contact ball bearings have raceways on the inner and outer rings, and the inner and outer rings can make relative displacement along the bearing axis. This type of bearing is particularly suitable for receiving composite loads, that is, loads that act simultaneously in the radial and axial directions. Angular contact ball bearing axial load acceptance ability increases with the increase of contact angle α. The contact angle is the angle between the line of contact points between the ball and the raceway in the radial plane and the vertical line of the bearing axis.

The types of angular contact ball bearings are divided into: α=15° angular contact ball bearings (70000C type); α=25° angular contact ball bearings (70000AC type); α=40° angular contact ball bearings (70000B type) ); back-to-back pairs of double angular contact ball bearings [70000C (AC, B)/DB type]; face-to-face pairs of double angular contact ball bearings [70000C (AC, B)/DF type.

Tandem paired double angular contact ball bearings [70000C (AC, B)/DT type]; double row angular contact ball bearings with a ball gap (type 00000); double row angular contact ball bearings without a ball gap (00000A Type); double row angular contact ball bearing without ball notch and dust cover on one side (type 00000A-Z); double row angular contact ball bearing without ball notch and dust cover on both sides (type 00000A-2Z) ).

Double-row angular contact ball bearing without ball notch and sealing ring on one side (type 00000ARS); double-row angular contact ball bearing without ball notch and sealing ring on both sides (type 00000A-2RS); four-point angular contact ball Bearing (QJ0000 type), 13 kinds in total.
