Structural features:

Basic structure: mainly composed of inner ring, outer ring, rolling element (steel ball) and cage. The raceways on the inner and outer rings are slightly larger than the radius of the rolling ball. The steel ball rolls between the inner and outer ring raceways. The cage is used to keep the steel balls at equal spacing so that they can roll smoothly.

Sealing form: There are two types: open and sealed. The sealed type is divided into various forms such as with dust cover, with non-contact rubber seal, with contact rubber seal, etc., which can prevent foreign matter from entering and lubricating oil from deteriorating.

Performance characteristics:

Load capacity: It can withstand radial loads and axial loads in two directions at the same time, and can adapt to the force requirements in different directions.

Friction characteristics: The inner and outer rings are in point contact with the steel ball, with small rolling resistance and extremely low friction torque. It can maintain low energy loss under high-speed rotation, reduce heat and wear.

Speed performance: The allowable speed is very high, suitable for occasions requiring high-speed rotation, and can maintain low noise and low vibration
