by 
It can bear radial load and axial load at the same time. It can work at high speed. The larger the contact angle, the higher the axial bearing capacity. High precision and high-speed Model bearings usually have a contact angle of 15 degrees. Under the action of axial force, the contact angle will increase.
Single row angular contact ball bearings can only bear axial load in one direction, which will cause Model additional axial force when bearing radial load. And can only limit the axial displacement of the shaft or housing in one direction. The contact angle of angular contact ball bearing is 40 degrees, so it can bear a large axial load.
Angular contact ball bearing is a non separable design, and the shoulders on both sides of the inner and outer Model rings are different. In order to improve the load capacity of the bearing, the shoulder on one side will be machined lower, so that the bearing can be loaded with more steel balls.
The double row angular contact ball bearing can bear the combined radial and axial load and torque load Model dominated by large radial load, which limits the axial displacement of the shaft in two aspects. It is mainly used in components that limit the bidirectional axial displacement of shaft and 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 internal clearance, bearing size, Model internal design and the force and torque acting on the bearing, while the large allowable tilt angle shall ensure that excessive additional stress will not be generated in the bearing.
If there is an inclination angle between the inner and outer rings of the bearing, it will affect the service life of the bearing, reduce the Model operation accuracy of the bearing and increase the operation noise. Double row angular contact ball bearings generally use nylon cage or brass solid cage.
During the installation of double row angular contact ball bearing, it should be noted that although the bearing can bear two-way axial load, if there is a ball loading gap on one side, it Model should be noted that the main axial load should not pass through the groove edge on the notched side. When using the bearing, pay attention to make the raceway on one side without ball loading notch bear the main load.
