Features:
1. Strong acid, alkali resistance, can also be used in Seawater.
2. High temperature and wear resistance, strength and hardness is almost the same from room temperature to 1200℃
3. Nonmagnetic, electrical insulation,  can also be used in magnetic field
4. Light weight with density 3.2g/cm3, 1/4 lighter than ordinary bearing materials.
5. High Hardness and high strength, hardness is twice of GCrls, elasticity modulus is 1/3 higher than GCrls.
6. Centrifugal force is small when rotating due to the low density.
7. Coefficient of Thermal Expansion is only 1/4 of GCrls, can be used in high temperature
8. Silicon Nitride has good self-lubricating, can work without lubricant.
9. Never rust

10. Silicon Nitride Balls can reach high precision because its structure is stable, not easy to cause deformation.

*Special packing requirement can be satified.
