Deep groove ball bearings are the most commonly used rolling bearings. It has a simple structure and is easy to use. It is mainly used to bear radial load, but when the radial clearance of the bearing is increased, it has a certain performance of angular contact ball bearing and can bear combined radial and axial loads. It can also be used to bear pure axial load when the rotational speed is high and the thrust ball bearing is not suitable. Compared with other types of bearings of the same size, this type of bearing has a small friction coefficient and a high limit speed. However, it is not resistant to impact and is not suitable for bearing heavy loads. Deep groove ball bearings are widely used in automobiles, tractors, machine tools, motors, water pumps, agricultural machinery, textile machinery, etc.
