Deep groove ball bearing is used to accommodate the pure radia load, it also can accommodate combined load of radia and axial. When it only accommodate pure raidal load, the contact angle is 0, it will own the same character as angle contact bearing and accommodate larger axial load when it has larger radial chearance.Deep groove ball bearing's friction coefficient is very small and extreme speed also is very high, particularly at the condition of the big axial load runs with high speed. it will own larger superiority than thrust ball bearing.

The structure of deep groove ball bearing is simple, besides the basic structure, it also has all kinds of deformation structure. it can used for transmission, instruments and meters, electric motor, electric appliance, internal combustion engines, traffic, agricultural machinery, construction machinery, construction machinery, etc.

Deep groove ball bearing is the most representative roller bearing and used widely. it is suitable for high speed's operation and has the capability of self-aligning, when it's shell hole tilts 2°-10°,it still can work normally, but it will influent the bearing's life.
