Application: Compared with single row bearings, double row 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 hubs of cars (some models also use double-row tapered roller bearings of the same size).


Features: The tiltability between the inner and outer rings of double row angular contact ball bearings is limited. The allowable tilt angle depends on the internal clearance of the bearing, the bearing size, the internal design and the forces and moments acting on the bearing, and the maximum allowable tilt angle. It should be ensured that no excessive additional stress is generated in the bearing.


If there is a tilt angle between the inner and outer rings of the 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 row angular contact ball bearings typically use a nylon cage or a brass solid cage. When installing double row angular contact ball bearings, it should be noted that although the bearing can bear the bidirectional 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 bearing, care should be taken to bear the main load on the side raceway without the ball gap.


Double row angular contact ball bearings are capable of withstanding large radial and axial bidirectional combined loads and moment loads, mainly radial loads, which limit the axial displacement of the shaft or casing in both directions with a contact angle of 30 degrees.


In addition, double row angular contact ball bearings also have good 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.
