Silicon Nitride Ball - Si3n4 Precision Ceramic | 59% Lighter Than Steel, Corrosion Resistant, High Temperature Resistance, Self-lubricating

We are exporting and producing of Silicon Nitride Ball in Dongguan, Guangdong, China to our clients.
Ceramic Si3N4 ball with good ability of isolation and no magnetism is the precision ceramic that fired in high temperature without oxidation air,which has the high intension, high wearing resistance, high temperature resistance,anti-canker,strong acid and alkali resistance,can be used in seawater for a long time. At 800, the intension and rigidity almost couldn't be changed, whose density is 3.20g/cm3 and is the 1/3 of the weight of bearing steel. There are small centrifugal force when circumgyrating and run at high speed.It also has the self-lubrication, and can be used in the environment with no lubricate medium and high pollution.which is the best material of Hybrid construction ceramic ball bearing.

Features:
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 1050C.
8. Never rust, and can roll without lubrication.
9. More corrosion resistant than steel.
