ceramic ball hybrid bearing
ceramic material has the advantages of low density, medium elastic modulus, small thermal expansion coefficient, high hardness, high temperature resistance, corrosion resistance, non-magnetic and so on. The hybrid ceramic ball bearings with zirconia and silicon nitride ceramic balls as rolling elements can significantly improve the contact fatigue life of the bearings and greatly expand the application fields of rolling bearings. They have been widely used in various high-precision, high-speed m
