Double row angular contact ball bearings can withstand larger radial loads, mainly combined radial and axial loads and moment loads, limiting the axial displacement of the shaft on both sides. Mainly used in components that limit the bidirectional axial displacement of the shaft and the housing.
The tiltability between the inner and outer rings of double row angular contact ball bearings is limited. The allowable tilt angle depends on the bearing’s internal clearance, bearing size, internal design, and the force and moment acting on the bearing, and the maximum allowable tilt angle should be guaranteed No excessive additional stress is generated in the bearing.
If there is an inclination angle between the inner and outer rings of the bearing, it will affect the life of the bearing, and at the same time cause the bearing’s running accuracy to decrease and the running noise to increase. Double row angular contact ball bearings generally use nylon cages or brass solid cages. Pay attention to the installation of double row angular contact ball bearings. Although the bearing can withstand two-way axial loads, if there is a gap for the ball on one side, care should be taken not to allow the main axial load to pass through the gap on the side of the groove. When using the bearing, pay attention to the main load on the side of the raceway without the ball-loading gap.

Compared with single row angular contact ball bearings, double row angular contact ball bearings have better rigidity and can withstand overturning moments. The bearing is non-separable. Especially suitable for applications with high rigidity requirements. Widely used in front wheels of cars.
The company processes and manufactures various and all kinds of international brand bearings.
