Angular contact ball bearings have raceways on the inner and outer rings, and the inner and outer rings can be displaced relative to each other along the axial direction of the bearing. These bearings are particularly suitable for withstanding composite loads, ie loads acting simultaneously in both radial and axial directions. The axial load bearing capacity of the angular contact ball bearing increases as the contact angle α increases. The contact angle is the angle between the line connecting the contact point of the ball and the raceway in the radial plane and the vertical line of the bearing axis.
The angular contact ball bearing models 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 paired double angular contact ball bearings [70000C (AC, B) / DB type]; face-to-face paired double angular contact ball bearings [70000C (AC, B) / DF type]; series paired double angle Contact ball bearings [70000C (AC, B) / DT type]; four point angular contact ball bearings (QJ0000 type). The material of the cage is brass, synthetic resin, etc., depending on the bearing type and the conditions of use.
