Deep groove ball bearing is the most commonly used rolling bearing. It is simple in structure and convenient to use. It is mainly used to bear the radial load, but when it enlarges the radial clearance of the bearing, it has the properties of the angular contact ball bearing, which can bear the diameter and axial combined load. It can also be used to bear the pure axial load when the rotating speed is not suitable for thrust ball bearing. Compared with other type bearings of the same size Jiashan oil-free bearing, the bearing Oil bearing friction coefficient is small and the limit speed is high. But it is not suitable to bear heavy load.

After the deep groove ball bearing is mounted on the shaft, the axial displacement of the shaft or the shell can be limited in the direction of the axial clearance of the bearing, so the Powder metallurgical bearing axial orientation of the axial direction can be made in both directions. In addition, the bearing also has a certain ability of regulating the core, which can still work normally when it is tilted 2 '~ 10' to the shell hole, but has certain influence on bearing life.

The deep groove ball bearing keeps the frame of the steel plate stamping wave form, and the large bearing is used to keep the frame.

Deep groove ball bearings are widely used in automobiles, tractors, machine tools, motors, pumps, agricultural machinery, textile machinery, etc.
