  Basic Knowledge Of Spark Bearing

  The bearing is a component that fixes and reduces the friction coefficient of the load in the process of mechanical transmission. It can also be said that when other mechanical parts move relative to each other on the shaft, they are used to reduce the coefficient of friction during power transmission and keep the shaft center position fixed. Bearings are an important part of contemporary machinery and equipment. Its m...
