52,53 series Duplex Ball Bearing

Angular contact ball bearings are the most repesentive of the rolling bearings,a wide range of uses.for speed operation,but also very durable,without regular maintenance.small coefficient of friction of such bearings,limte high-speed,simple structure,low mannufactringcost and easy to reach a higher mannufacturing precision.

Compared with single-row bearings, double-row angular contact ball bearings have better rigidity and can withstand overturning torque. The bearing is non-separable,especially suitable for applications with high rigidity requirements.
It is widely used in front wheel hubs of small cars (some models also use double-row tapered roller bearings of the same size).

Application

It is mainly used for limiting axial displacement of shaft and shell. The tilting between inner and outer ring of double row angular contact ball bearing is limited, the allowable tilt angle depends on the internal clearance of the bearing, bearing size, internal design and the force and torque acting on the bearing, and the maximum allowable tilt angle should ensure that the bearing will not produce excessive additional stress.

If there is a tilt angle between the inner and outer rings of the bearing, the life of the bearing will be reduced, and the running accuracy of the bearing will be also reduced ,but the running noise will be increased.

Double row angular contact ball bearings generally use nylon cage or brass solid cage.

Attention should be paid to the installation of double-row angular contact ball bearing.

Although the bearing can bear two-way axial load, if there is a ball loading gap on one side, it should be noted that the main axial load should not pass through the groove side with a gap.When the bearing is used, it should be noted that the raceway on one side without the gap of ball loading should bear the main load.
