What’s the characteristics of double angular contact ball bearing?

The design of the double angular contact ball bearing is basically the same as that of a single row angular contact ball bearing, but only takes up less axial space. The double angular contact ball bearing can withstand radial loads and axial loads acting in both directions. It limits the axial displacement of the shaft or casing with a contact angle of 30 degrees. The double angular contact ball bearing provides a highly rigid bearing arrangement and can withstand overturning moments.

The application range of double angular contact ball bearing:

Double angular contact ball bearing Compared to single row angular contact ball bearings, double angular contact ball bearings have better rigidity and can withstand overturning moments. The bearings are non-separable. Especially suitable for applications with high rigidity requirements. Widely used in the front wheel hub of a car (some models also use double-row tapered roller bearings of the same size).

Double angular contact ball bearing performance characteristics
Double angular contact ball bearing has limited inclination between the inner and outer rings. The allowable inclination angle depends on the internal clearance of the bearing, the bearing size, the internal design and the force and moment acting on the bearing, and the maximum allowable inclination angle should ensure the bearing. There is no excessive additional stress in the interior.If there is a tilt angle between the inner and outer rings of the double angular contact ball bearing, it will affect the life of the bearing, and at the same time, the bearing running accuracy will decrease and the running noise will increase. Double angular contact ball bearings are generally nylon cages or brass solid cages. Double angular contact ball bearing should be noted that although the bearing can bear the two-way axial load, if there is a ball gap on one side, care should be taken not to let the main axial load pass through the notched side groove. When using the double angular contact ball bearing, care should be taken to apply the main load to the side raceway without the ball gap.
