The design of double-row angular contact ball bearings is basically the same as that of single-row angular contact ball bearings, but it only takes up less axial space. Double-row angular contact ball bearings can withstand radial loads and axial loads acting in two directions. It can limit the axial displacement of the shaft or housing in two directions. The contact angle is 30 degrees. Can provide high rigidity bearing configuration, and can withstand overturning moment.

Compared with single-row angular contact ball bearings, double-row angular contact ball bearings have better rigidity and can withstand overturning moments. The bearings are non-detachable. Especially suitable for applications with high rigidity requirements. Widely used in the front wheel hub of cars (Some models also use double-row tapered roller bearings of the same size)

The tiltability between the inner and outer rings of double row angular contact ball bearings is limited. The allowable tilt angle depends on the internal clearance of the bearing, the bearing size, the internal design, and the forces and moments acting on the bearing. There will be no excessively high additional stress in the bearing.

If there is an angle of inclination 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 cage or brass solid cage. Double-row angular contact ball bearings should be installed with attention. Although the bearings can withstand two-way axial loads, if there is a ball gap on one side, care should be taken not to let the main axial load pass through the groove side of the gap. When using the bearing, pay attention to make the side raceway without ball gap bear the main load
