Angular contact ball bearing
 
Single row angular contact ball bearings can only bear axial load in one direction. When bearing radial load, additional axial force will be caused. And only limit the axial displacement of the shaft or housing in one direction. Angular contact ball bearings have a contact Angle of 40 degrees, so they can withstand a large axial load. Angular contact ball bearings are non - separation design, the inner and outer rings of the two sides of the shoulder height. To increase the bearing's load capacity, one of the shoulders is machined lower so that more steel balls can fit into the bearing.

Double row angular contact ball bearings can bear large radial load mainly radial and axial combined load and torque load, limiting the axial displacement of both sides of the shaft. Is mainly used for two-way axial displacement limit shaft and the shell parts of double row angular contact ball bearing can be skewed between inner and outer ring is limited, allowing Angle depends on the bearing internal clearance, bearing on the size, in the role of interior design, and the bearing force and moment, and the maximum allowable slope Angle should guarantee won't produce high additional stress 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 the running accuracy of the bearing will be decreased and the running noise will be increased. Double row angular contact ball bearings are usually made of nylon or brass solid cage. 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 ball loading gap on one side, it should be noted that the main axial load should not pass through the notch on the side of the groove. When the bearing is in use, care should be taken to make the side raceway without ball loading notch bear the main load.
