Product Description

Silicon Nitride Ceramic Bead For Grinding

Product Description
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
. Superior surface finish can be achieved, Ra could be 4~6 nm
7. Can endure high temperature with high hardness and strength up to 1100°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.
 
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.
