Double row angular contact ball bearings can bear large radial loads, combined radial and axial loads and torque loads, which are mainly used to limit the axial displacement of shaft and shell. Such as: [SKF double row angular contact ball bearing with two back-to-back arrangement on the design of single contact ball bearing is similar, but the width slightly narrower than two single bearing. Compared with single bearing has better rigidity, can withstand the overturning moment. Bearing as a separate. There is a requirement for high rigidity is particularly suited to applications. Widely used in the front wheel hub of the car.

The inclination between the inner and outer rings of double row angular contact ball bearings is limited. The allowable inclination Angle depends on the internal clearance of the bearing, bearing size, internal design and the force and moment acting on the bearing. The maximum allowable inclination Angle should ensure that excessive additional stress will not be generated in the bearing. If there is an inclination Angle between the inner and outer rings of the bearing, the life of the bearing will be affected, and the running accuracy of the bearing will decrease, and the running noise will increase. Double row angular contact ball bearings generally use nylon cage or brass solid cage. When installing double row angular contact ball bearings, it should be noted that although the bearings can withstand two-way axial load, if there is a ball gap on one side, it should be noted not to let the main axial load pass through the notch on one side. In the use of bearings, attention should be paid to the side of the raceway without ball loading gap to bear the main load.
