There are raceways on the inner and outer rings of angular contact ball bearings, and the inner and outer rings can make relative displacement along the bearing axis. This type of bearing is particularly suitable for bearing compound loads, namely, the load acting both radially and axially. Axial load bearing capacity of angular contact ball bearing follows contact angle α And increase. The contact angle is the angle between the contact point line of the ball and raceway in the radial plane and the vertical line of the bearing axis.

The models of angular contact ball bearings are divided into: α= 15 ° angular contact ball bearing (70000C type); α= 25 ° angular contact ball bearing (70000AC type); α= 40 ° angular contact ball bearing (70000B type); Back-to-back double angular contact ball bearing [70000C (AC, B)/DB type]; Face-to-face double angular contact ball bearing [70000C (AC, B)/DF type]; Series paired double angular contact ball bearing [70000C (AC, B)/DT type]; Double-row angular contact ball bearing with ball gap (00000 type); Double-row angular contact ball bearing without ball gap (00000 A type); Double-row angular contact ball bearing (00000 A-Z type) without ball gap and with dust cover on one side; Double-row angular contact ball bearing (00000 A-2Z type) without ball loading gap and with dust cover on both sides; Double-row angular contact ball bearing (00000 ARS type) without ball gap and with sealing ring on one side; Double-row angular contact ball bearing (00000 A-2RS type) with sealing rings on both sides without ball loading gap; Four-point angular contact ball bearing (QJ0000 type), 13 types in total.
