  Deep groove ball bearing

Advantages of deep groove ball: The deep groove ball bearing is the most representative rolling bearing, which is widely used. It is suitable for operation at high speed or even extremely high speed, and it is very durable without regular maintenance. This kind of bearing has small friction coefficient, high limit speed, simple structure, low manufacturing cost and high manufacturing accuracy. With various size ranges and forms, it is widely used in precision instruments, low-noise motors, automobiles, motorcycles and general machinery industries. It is the most widely used type of bearing in the machinery industry. It mainly bears radial load, but also can bear a certain amount of axial load.
