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 large axial loads. Angular contact ball bearings are of a non-separable design with different shoulders on both sides of the inner and outer rings. In order to increase the bearing load capacity, one shoulder is machined lower so that the bearing can hold more steel balls.

Double row angular contact ball bearings can withstand the combined radial and axial loads and torque loads, which are mainly radial loads, and limit the axial displacement of the two aspects 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 life of the bearing will be affected, and the running accuracy of the bearing will decrease, and the running noise will increase. Double row angular contact ball bearings generally use nylon cage or brass solid cage. When installing double row angular contact ball bearings, it should be noted that although the bearings can withstand two-way axial load, if there is a ball gap on one side, it should be noted not to let the main axial load pass through the notch on one side. In the use of bearings, attention should be paid to the side of the raceway without ball loading gap to bear the main load.
