Silicon Nitride Bearing Rollers, Si3N4 bearing roller
Silicon nitride is has excellent thermal shock resistance due to the microstructure. The creep and oxidation resistance of Si3N4 is also superior, its low thermal conductivity and high wear resistance also make it an outstanding material that can withstand conditions of most industrial applications. Silicon Nitride ceramic is ideal for bearing rollers.

Packing of Silicon NitrideCeramics
As a ceramic material, silicon nitride is quite fragile in a lot of cases. Our silicon nitride bearing rollers are carefully handled to minimize damage during storage and transportation. Suitable outer boxes and inner cushioning materials are used for Si3N4products, vacuum packing is also engaged for some of the parts.
