  • High speed 7900C Miniature Bearings for motor

    Single row angular contact ball bearings can only bear axial load in one direction. When bearing radial load, the additional axial force will be caused. And it can only limit the axial displacement of the shaft or housing in one direction. Angular contact ball bearings have a contact angle of 40 degrees, so they can withstand large axial loads. Angular contact ball bearings are of a non-separable design, and the shoulders on both sides of the inner and outer rings are different in height. In order to improve the load capacity of the bearing, the shoulder on one side will be processed lower so that the bearing can be loaded with more steel balls.
