Double-row angular contact ball bearing can bear the combined radial and axial load and torque load mainly with large radial load, and limit the axial displacement of the shaft in both directions. The inclinability between the inner and outer rings of the double-row angular contact ball bearing, which is mainly used to limit the bidirectional axial displacement of the shaft and the shell, is limited. The allowable inclination angle depends on the internal clearance of the bearing, the bearing size, the internal design and the forces and moments acting on the bearing. The maximum allowable inclination angle should ensure that there is no excessive additional stress in the bearing. If there is a tilt angle between the inner and outer rings of the bearing, the service life of the bearing will be affected, and the operating accuracy of the bearing will be reduced, and the operating noise will be increased. Double row angular contact ball bearings generally use nylon cages or brass solid cages. 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 loading notch on one side, it should be noted that the main axial load should not pass through the groove edge on the notch side. When using the bearing, attention should be paid to make the raceway on the side without the ball notch bear the main load.
