Features of Ceramic ball : -ZRO2, SI3N4, SIC

1.59% lighter than steel ball, which means less centrifugal force and less wear on the groove during high speed and acceleration.
2.44% larger elastic modulus, which means less deformation under load.
3. Harder with Rockwell hardness as 78.
4. Smaller friction coefficient.
5. Only 1/4 coefficient of thermal expansion of steel, can endure sharp fluctuation of temperature.
6. Superior surface finish can be achieved.
7. Can endure high temperature with high hardness and strength up to 1050C.
8. Never rust, and can roll without lubrication.
9. More corrosion resistant than steel.
10. Free of metal contamination.
11. Non-magnetic.
12. Electric isolation. 
 

Application of Ceramic Ball:

Ceramic ball is generally assembled in bearing for application in high-tech industry such as aerospace, national defense, chemical industry, metallurgical, medical, food, oil plant, electronic etc.
