Angular contact ball bearing has a high limit speed, which can bear radial load and axial load at the same time, and can also bear pure axial load. Its axial load capacity is determined by the contact angle and increases with the increase of the contact angle. Big.

　　Single row angular contact ball bearing can only bear axial load in one direction. When bearing radial load, it will cause additional axial force, which must be applied to the corresponding reverse load, so , This kind of bearings are generally used in pairs. Double row angular contact ball bearings can withstand large radial and axial bidirectional combined loads and moment loads, which are dominated by radial loads. It can limit the axial displacement of the shaft or housing in both directions, with a contact angle of 30 degrees.

　　The angular contact ball bearings installed in pairs can withstand the combined radial and axial bidirectional load based on the radial load, as well as the pure radial load. The tandem configuration can only bear axial load in a single direction, and the other two configurations can bear axial load in either direction. This type of bearing is generally selected and combined by the manufacturer and submitted to the user in pairs. After installation, there is preload interference, and the ring and steel ball are in the axial preload state, thus increasing the rigidity and rotation of the entire group of bearings as a single support Accuracy.
