Single-row angular contact ball bearings are suitable for bearing raidal loads and axial loads in one direction or synthetic loads due to contact angles . In the structure, the axial component force is generated after receiving the radial load so that the two bearings are used for the opposite use, or the two or more bearings are used in combination .
The contact angle of angular contact ball bearing is different , even when bearing is with the same load , the load state of the contact part of the ball and inner and outer ring is different, and the elastic deformation or the stress of the contact part are also different .
