PDF

Product Information

The basic structure of a deep groove ball bearing consists of an outer ring, inner ring, steel balls, and a cage. Its raceway is a deep, continuous, curved groove, which gives it the following outstanding characteristics:

Versatile versatility

High speed capability

Low frictional torque and high efficiency

Simple structure and low manufacturing cost

Low noise and low vibration

Main application areas：

Deep groove ball bearings are ubiquitous, covering almost all industrial fields and everyday appliances:

Electric motors/generators: Standard configuration for small and medium-sized motors.

Automotive: Auxiliary components other than the wheel hub (such as generators, tensioners, gearboxes).

Home appliances: Air conditioners, washing machines, vacuum cleaners, fans, etc.

General machinery: Gearboxes, pulleys, pumps, agricultural implements.

Office equipment and precision instruments: Computer hard drives, optical drives, small measuring instruments.
