4.762mm Zirconium Oxide Bearing Balls/ZrO2 Ceramic 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 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 1050 ℃.

8. Nevr 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 Zirconia ball

ZrO2 ball is mainly used for valve ball, full ceramic bearing, metering ball, track ball and precision grinding ball. It can be used in fields requiring chemical resistance, high temperature, electronic insulation, magnetic insulation, non-lubrication. ZrO2 ball is an idea substitute for steel ball in chemical corrosion application. As valve ball, ZrO2 ball is now successfully used in high pressure homogenizer, diaphragm pump, metering pump, oil well pump, high pressure sprayer etc.
