Doulbe Row Angular Contact Ball Bearing
Doulbe Row Angular Contact Ball Bearing

Double row angular contact ball bearings can withstand radial loads and axial loads acting in both directions, it can limit the shaft or housing two-way axial displacement, the contact Angle is 30 degrees. High rigidity bearing configurations are available and can withstand overturning moments.


Apply

Double row angular contact ball bearings have better rigidity and can withstand overturning moment. Bearings are non-separated. Especially suitable for applications with high rigidity requirements. It is widely used in the front wheel hub of the car (some models also use double row tapered roller bearings of the same size).


Peculiarity

The inclinability between the inner and outer rings of double-row angular contact ball bearings is limited, and 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 that there is no excessive additional stress in the bearing.


If the inclination Angle between the inner and outer rings of the bearing exists, the life of the bearing will be affected, and the running accuracy of the bearing will be reduced, and the running noise will be increased. Double row angular contact ball bearings generally use nylon cages or brass solid cages. When installing double row angular contact ball bearings, attention should be paid to the fact that although the bearings can withstand two-way axial loads, if there is a ball loading gap on one side, care should be taken not to let the main axial load pass through the groove side with a gap. When the bearing is used, attention should be paid to making the raceway without the ball filling gap bear the main load.


In addition, double row angular contact ball bearings also have good rigidity and can withstand overturning moment. Bearings are non-separated. Especially suitable for applications with high rigidity requirements. It is widely used in front wheel hubs of cars.
