Deep groove ball bearing is the most commonly used rolling bearing. Its structing is simple, and it can be easy to operate. They are mainly used for standing the radial lod. But when the radial play is increasing, they have the proformance of angular contact bearing assembly. In that case, they may simultaneously stand the radial loads and the axial loads. Compared with other kind of bearing enjoy smaller conefifcient of friction and higher limits speed. But they cannot bear impact. Therefore they are not suittable the bear heavy load. The deep groove ball bearing can be widely used in automobile, tractor, engine bed, electrical machinery, water pump, agricultural machinery and fabrics machine.
