Single row angular contact ball bearings can withstand axial load in one direction

Single row angular contact ball bearings can withstand axial load in one direction, while the radial load, will cause additional axial force. And the only limit axial displacement in one direction shaft or housing. Angular contact ball bearings contact angle of 40 degrees, so you can bear large axial load. Angular contact ball grinding spindle are non-separable design, inner and outer rings on both sides of the shoulder uneven. In order to improve the load bearing capacity, in which the shoulder side of the processing will be lower, so that the ball bearings can be put more.
Double row angular contact ball bearings can withstand greater radial load mainly radial and axial joint load and moment load limit axial displacement both axes. Mainly used to limit the axial displacement of the shaft and housing components in a two-way double row angular contact ball bearings, the outer ring can be tilted between finite, allowing the tilt angle depends on the bearing internal clearance, bearing size, interior design and acting on forces and moments on the bearings, and the maximum allowable tilt angle should ensure that the bearing will not generate excessive additional stress. If the bearing inner and outer angle of inclination between, will affect Bearing life testing machine life, also causing loss of precision bearings running, running noise increases. Double row angular contact ball bearings generally use nylon cage or solid brass cage. When the double row angular contact ball bearings installed should be noted that while bearings can withstand axial load, but if one side of the ball gap, you should be careful not to let the main axial load side through the gap Mizobe. Bearings should pay attention to the side without the ball gap to bear the main load raceway.
