Top quality ceramic polishing ball

 Features of Ceramic Ball:

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 92

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 up to 1050°C

8. Never rust, and can roll without lubrication.

9. More corrosion resistant than steel.

Application of Zirconia ball

Si3N4 be first choice for high-demand bearing ball material and valve ball. Si3N4 ball can also be used as valve ball and metering ball in chemical pump, high-temperature pump, metering pump. Si3N4 ball can also be used in linear slider for high temperature and corrosion resistance.
