Miniature bearings are generally suitable for high speed, low friction torque, low vibration, low noise environment products, is a widely used bearings. Miniature bearings are suitable for all kinds of industrial ……

Cixi double row deep groove ball shaft - shaped raceway plus between the raceway and the steel ball has excellent fit. 

Since the mobile contact can make the starting friction resistance and the dynamic friction resistance are very small, it can save energy and get a higher speed of motion easily.

According to the rotation of the imported bearing, there are three kinds of loads: local load, cyclic load and swinging load.
