Deep Groove Ball Bearings can mainly carry  radial load,as well as certain axial load.When the radial clearance is increased,the deep groove ball bearing has the function of contact angle,and also carry heavy axial load .Compared with other types of the same size,the friction coefficient of this type is small,the most limite rotate speed is fast.In the case of that,this type of bearing can be instead of thrust bearings to bear the radial load.
