Silicone Nitride Ceramic Wafer Material Description : 

Silicon nitride ceramic material has high hardness, low density, wear resistance and high temperature resistance. The rolling body is made of silicon nitride ceramic, while the other components are paired with bearing steel to form friction pair, the friction coefficient is extremely low, and it is not easy to stick and glue with the cage.Therefore, it has been considered as the preferred material for manufacturing high-speed and precision bearings. 

Silicone Nitride Ceramic Wafer  Features are as follows:

1. High rigidity, high strength and high hardness.

2. Strong corrosion resistance, can be used in strong acid and strong alkali.

3. High temperature resistant, silicon nitride ceramic balls under 1000 ? environment can be normal use.

4. Non-magnetic and electrical insulation.

5. Low density (3.26g/cm3), about 60% lighter than steel ball, reducing wear and noise.

6. The low linear expansion coefficient (3.2 * 10-6/K), almost 1/4 of the bearing steel, can withstand the rapid change of temperature.

7. Self-lubricity, can solve the pollution caused by the lubrication medium and add inconvenience, can be used in vacuum and high temperature.

8. Drug resistance, high mechanical strength, low thermal conductivity.
