Double Row Angular Contact Ball Bearings

● The design of double-row angular contact ball bearings is basically the same as that of single-row angular contact ball bearings, but occupies less axial space. ● Can bear radial load and axial load acting in two directions, it can limit the axial displacement of the shaft or housing in two directions, the contact Angle is 30 degrees. ● Provides high rigidity bearing configuration, and can withstand overturning torque. ● Widely used in the front wheel hub of a car.

Products Details

The design of double-row angular contact ball bearings is basically the same as that of single-row angular contact ball bearings, but occupies less axial space. The double-row angular contact ball bearing can bear radial load and axial load acting in two directions, it can limit the axial displacement of the shaft or housing in two directions, the contact Angle is 30 degrees. Provides high rigidity bearing configuration, and can withstand overturning torque.Compared with single row angular contact ball bearing, double row angular contact ball bearing has better rigidity and can withstand overturning torque. The bearing is of non-separating type. It is especially suitable for applications with high rigidity requirements. ●Less axial space Can be used for applications where two single row angular contact ball bearings arranged back-to-back take up too much axial space. Accommodates radial as well as axial loads in either direction Accommodates tilting moments Stiff bearing arrangementWidely used in the front wheel hub of a car. Application for oil pumps, Roots blowers, air compressors, various transmissions, fuel injection pumps, printing machinery, planetary reducers, extraction equipment, cycloid reducers, food packaging machinery, electric welding machines, electric soldering irons, square boxes, gravity spray guns, Wire stripping machine, half shaft, inspection and analysis equipment, fine chemical machinery.The inclinability between the inner and outer rings of the double-row angular contact ball bearing is limited. The allowable inclinability depends on the internal clearance, bearing size, internal design and the force and moment acting on the bearing. The maximum allowable inclinability should ensure that the bearing does not generate excessive additional stress. If there is an inclination Angle between the inner and outer rings of the bearing, it will affect the life of the bearing and cause a decrease in the running accuracy of the bearing and an increase in the running noise. Double row angular contact ball bearings are generally made of nylon or brass retainers. When installing double-row angular contact ball bearings, it should be noted that although the bearing can bear two-way axial load, if there is a ball gap on one side, it should be noted that the main axial load should not pass through the notch on one side of the ditch. Care should be taken to make the raceway on one side without the ball gap bear the main load when the bearing is in use.
