Silicon Nitride balls

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.
