Deep groove ball bearings are the most commonly used rolling bearings. It is generally composed of a pair of ferrules, a set of cages, and a set of steel balls. Its structure is simple and easy to use. 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 load. It can also be used to bear pure axial load when the speed is high and thrust ball bearing is not suitable. Compared with other types of bearings with the same specifications and dimensions of deep groove ball bearings, this type of bearing has a small friction coefficient and a high limit speed. But not impact resistant, not suitable for heavy loads
