Deep groove ball bearing inner and outer ring raceway are circular arc shaped deep groove, slightly larger than the channel radius of the sphere. Is mainly used to bear radial load, also can absorb a certain amount of axial load. When bearing radial clearance increases, has the function of angular contact ball bearings can withstand large axial load, and is suitable for high speed spinning. Bearing on the shell holes and axis tilted relative '8 ~ 16', can still work normally, but affect the service life. In high speed and should not be used under the condition of thrust ball bearing can be used the bearing pure axial load.

Deep groove ball bearings generally adopt a synthesized from two parts stamping steel cage, but large size or the entity will be used on high speed bearing cage, the cage like punching cage guided by the ball, the deep
