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.
