The inclination between the inner and outer rings of the angular contact ball bearing is limited. The allowable inclination depends on the internal clearance, bearing size, internal design and the force and torque acting on the bearing. The maximum allowable inclination shall ensure that no excessive additional stress will be generated in the bearing.

f there is an inclination angle between the inner and outer rings of the bearing, the service life of the bearing will be affected, and the running accuracy of the bearing will be reduced and the running noise will be increased. Generally, double row angular contact ball bearing adopts nylon cage or brass solid cage. During the installation of double row angular contact ball bearing, it should be noted that although the bearing can bear two-way axial load, if there is a ball mounting gap on one side, it should be noted that the main axial load should not pass through the groove edge of the notched side. When using the bearing, pay attention to make the side raceway without the ball loading notch bear the main load.
