If the bearing inner and outer angle of inclination between

If the bearing inner and outer angle of inclination between, will affect bearing 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  high precision bearing  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.bearing manufacturer More angular contact ball bearings are Bearing manufacturing machine  manufactured abroad bearing manufacturers, domestic applied to imported equipment such as more angular contact ball bearings 3204RS, etc.
Think back to back, back to front contact contact more simple, narrow side out, including wide-brimmed, another broadside included, narrow home, is back to back contact.
