Angular Contact Ball Bearings can withstand both radial and axial loads simultaneously. Capable of operating at higher speeds. The larger the contact angle, the higher the axial bearing capacity. The contact angle is the angle between the contact point line between the ball and raceway in the radial plane and the vertical line of the bearing axis. High precision and high-speed bearings typically have a contact angle of 15 degrees. Under the action of axial force, the contact angle will increase.

Angular contact ball bearings have raceways on both the inner and outer rings, and the inner and outer rings can move relative along the bearing axis. This type of bearing is particularly suitable for bearing composite loads, i.e. loads acting both radially and axially. The axial load bearing capacity of angular contact ball bearings varies with the contact angle α Increase with the increase of. The contact angle is the angle between the contact point line between 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 ° angle contact ball bearing (70000C type); α= 25 ° angular contact ball bearing (70000AC type); α= 40 ° angle contact ball bearing (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 angular contact ball bearings [70000C (AC, B)/DT type]; Double row angular contact ball bearings with ball mounting gaps (00000 type); Double row angular contact ball bearings without ball gaps (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 bearings without ball gaps and with dust covers on both sides (00000 A-2Z type); Double row angular contact ball bearing (00000 ARS type) without ball gap and with sealing ring on one side; Double row angular contact ball bearings with sealing rings on both sides without ball gaps (00000 A-2RS type); There are 13 types of four point angular contact ball bearings (QJ0000 type).
