Angular contact ball bearings are under high one-way axial load, the larger the contact Angle, the greater the load capacity. Cage material with steel, brass or engineering plastic, stamping or cutting molding way, depending on the bearing form or use different selection. There are other combination angular contact ball bearing, double row angular contact ball bearing and four-point contact ball bearing.

Angular contact ball bearings can bear radial load and axial load at the same time. Can work under high speed. The larger the contact Angle, the higher the axial bearing capacity. High precision and high speed bearing contact Angle usually take 15 degrees. Under the effect of axial force, the contact Angle increases. Single row angular contact ball bearings can only carry axial load in one direction, when bear radial load, will cause the additional axial force. And only limit shaft or shell axial displacement in one direction. If double installed in pairs, make a pair of bearing outer ring relative, namely the wide end facing the wide end face, the narrow end face the narrow end. This can avoid the additional axial force, but also can be in two directions the shaft or shell limits in the range of the axial clearance.
