Product Details
Product Description
Ceramic Ball Bearings, also called hybrid bearings, are a component that can easily optimize application performance. The thermal expansion coefficient of the ceramic ball is small, and the bearing ball will not expand due to temperature in a high temperature environment, which greatly increases the operating temperature of the entire bearing. In addition, Ceramic Ball Bearings can operate in harsh environments due to their anti-corrosion and anti-corrosion properties. Their electrical insulation properties eliminate the risk of electrical corrosion and pitting of the rolling elements.
Advantages
Ceramic Ball Bearings are stronger, harder and more wear-resistant than steel bearings, thereby extending the life of the machine. It has been widely used in various high-precision, high-speed machine tools, automobiles, racing cars, subways, electric motors, aero engines, petrochemical machinery, metallurgical machinery and other fields. If you have any questions or needs for the product, please communicate with us in time.
