As for contact angle A, Angular contact ball bearings can bear both radial load and axial load.

Contact Angle is defined as angle between steel ball and groove contact with radial plane. The raceway of inner ring and outer ringof angular contact ball bearing has a relatively displacement in horizontal axis, so it can both bear radial load and axial load - union load (single Angle contact ball bearing can only carry single direction axial load, so usually adopted installed in pair). Cage material includes brass, synthetic resins, et, the bearings form, in accordance with the using conditions and divisional.

Single Angular contact ball bearing

Single Angular contact ball bearing can bear radial and axial load. This type of bearing although can only sustain one-way axial load,it can combine with another bear reverse load. Angular contact ball bearing is unseperatable. Angular contact ball bearing suitable for high speed with limited automatically adjustable ability.
