Since the ceramic ball bearing is an important mechanical base part, it has excellent performances the metal bearing can’t match. Therefore, it has been increasingly widely used in various fields. Judged on the effect of the application, the most prominent effect is to greatly improve the bearing life and limit speed, providing basic components for the development of high-speed and high-precision machine tools. In addition, the ceramic ball bearing has also achieved good results in the industry of high temperature, corrosion, insulation, vacuum and other industries. Based on its wide applications, it has brought greater vigor and vitality for its development.
