Si3N4 Ceramic ball
Compared with steel ball, WOW Ceramic ball has following advantages:
1. Lighter than steel ball, which means less centrifugal force and less wear on the groove during high speed and acceleration.
2 Llarger 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, Ra could be 4~6 nm.
7. Can endure high temperature with high hardness and strength
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.
13. No adhesive-wear.
Application:
can be used in all bearings with special requirement;
can be used as valve ball and metering ball in chemical pump, high-temperature pump, metering pump;
generally assembled in bearing for application in high-tech industry such as aerospace, national defense, chemical industry, metallurgical, medical, food, oil plant, electronic etc.
