Compared with steel ball, Si3N4 ball has following advantages:

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, 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.

10. Free of metal contamination.

11. Non-magnetic

12. Electric isolation

13. No adhesive-wear with metal

14. Contact angular is very large with molten and nearly no reaction

All above combination makes Si3N4 to be first choice for high-demand bearing ball material and valve ball

 

Application:

Si3N4 ball can be used in all bearings with special requirement: high speed bearing, high precision bearing; vacuum bearing; high/low temperature bearing, non-magnetic bearing, high precision ball screw; 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.

Note:

1. Black color as standard, gray color could be supplied upon customer requirement

2. Non-standard size and different gauge could be supplied
