Factory supply Angular Contact Ball Bearing for railway mining machines

Double row angular contact ball bearings can withstand larger radial loads and combined radial and axial loads and moment loads, limiting the axial displacement of the shaft on both sides.

The inclination between the inner and outer rings of the double row angular contact ball bearing is limited in the components that are mainly used to limit the bidirectional axial displacement of the shaft and the housing. The allowable inclination angle depends on the internal clearance of the bearing, bearing size, internal design and the effect on forces and moments on the bearing, and the maximum allowable inclination angle should ensure that excessive additional stress is not generated in the bearing.

If there is an inclination angle between the inner and outer rings of the bearing, the service life of the bearing will be affected, and at the same time, the running accuracy of the bearing will decrease and the running noise will increase. Double row angular contact ball bearings generally use nylon cages or brass solid cages.

When installing the double row angular contact ball bearing, it should be noted that although the bearing can bear bidirectional axial load, if there is a gap for the ball on one side, care should be taken not to let the main axial load pass through the groove on the side with the gap.

When the bearing is used, care should be taken to make the side raceway without the ball-loading notch bear the main load.

The special feature of angular contact ball bearings is that there is a contact angle between the ring and the ball.

The standard contact angles are 15°, 30° and 40°; the larger the contact angle, the greater the axial load capacity, and the smaller the contact angle, the greater the Conducive to high-speed rotation; single-row bearings can withstand radial load and unidirectional axial load.
