4point angular contact ball bearing, Feature,
1. The angular contact ball bearing has a high limit speed, which can bear both radial load and axial load as well as pure axial load. Its axial load capacity is determined by the contact Angle and increases with the increase of the contact Angle.
2. Single row angular contact ball bearing can only bear one direction of the axial load, in the radial load, will cause additional axial force, must be applied to the corresponding reverse load, therefore, the bearing is generally used in pairs.
