In the mechanical world, there is a mysterious part responsible for reducing friction and bearing the load, it is - ball bearings. So, why do mechanical devices prefer it? This is not only the technical preference of engineers, but also the ultimate pursuit of "efficiency".

Grease should be no stranger to everyone, is a widely used lubricant. Various types of greases are used in daily mechanical repair, including sodium base, calcium base, lithium base, barium base, aluminum base grease, etc., to ensure the normal operation of the operating parts of the equipment.

Vibration is the source of noise, bearing noise and vibration are inseparable, in order to ensure low vibration and low noise bearing work, must be from the bearing quality and motor bearing structure design, bearing support processing technology, bearing maintenance and other aspects of a comprehensive consideration. Adopt reasonable design structure, advanced processing technology, correct use and maintenance to reduce bearing noise and extend bearing life.

The bearing model generally has a pre-code, a basic code and a post-code. In general, the bearing model is only indicated by the basic model.

Compared with large machinery, the bearing is a small component, but it plays a pivotal role.
