Ceramic ball bearings are high-performance bearings, among which silicon nitride ceramic ball bearings are the most widely used ceramic balls. They have the advantages of high temperature resistance, corrosion resistance, longer service life and high rigidity. They are widely used in aerospace, auto

Ordinary rolling bearings are composed of rings, rolling elements, retainers, grease, and seals. When the rolling elements are made of ceramic materials, the rolling bearings are defined as hybrid ceramic ball bearings. Comparison of the properties of four bearing materials: ordinary bearing steel A
