[0002] Deep groove ball bearings, formerly known as radial ball bearings, are the most widely used rolling bearings. They are characterized by low friction resistance and high speed. They can be used on parts that bear radial loads or combined loads of radial and axial loads at the same time, and can also be used on parts that bear axial loads, such as low-power motors, automobile and tractor gearboxes, machine tool gearboxes, general machines, tools, etc.

[0003] The deep groove ball bearing in the prior art mainly comprises a bearing outer ring, a bearing inner ring, a bearing retainer and a bearing ball. When in use, the bearing ball is fixed to the bearing retainer and then installed with the bearing outer ring and the bearing inner ring.
