China Double Row Angular Contact Ball Bearing 3211atnwheel Bearing

Double row angular contact ball bearing
Application: compared with single row bearing, double row angular contact ball bearing has better rigidity and can bear overturning moment. The bearing is non separating type. It is especially suitable for applications with high rigidity requirements. It is widely used in the front wheel hub of cars (some models also use double row tapered roller bearings of the same size).
Features: the tilting between the inner and outer rings of double row angular contact ball bearings is limited. The allowable tilting angle depends on the internal clearance, bearing size, internal design and the force and moment acting on the bearing, and the maximum allowable tilting angle shall ensure that there is no excessive additional stress in the bearing.
If 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.
The double row angular contact ball bearing can bear large combined radial and axial loads and moment loads, which are mainly radial loads. It can limit the axial displacement of the shaft or shell in both directions, and the contact angle is 30 degrees.
