Advantages
The silicon nitride ceramic material has high hardness, low density, wear resistance and high temperature resistance. The rolling body is made of silicon nitride ceramic, and other parts are paired with bearing steel to form a friction pair, which has a very low friction coefficient and is not easy to stick to the cage, so it is considered to be the preferred material for manufacturing high-speed precision bearings.
