High quality small  Silicon Si3N4 ball/Ceramic ball

 Features of Ceramic Ball:

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 92

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, Ra could be 4~6 nm

7. Can endure high temperature with high hardness and strength up to 1050°C

8. Never rust, and can roll without lubrication.

9. More corrosion resistant than steel.

Table of material performance

Application of Zirconia ball

Si3N4 be first choice for high-demand bearing ball material and valve ball. 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.

ion Process

Each type ball has its special production process. However, the production process can be generalized as following:

 Packing: plastic bag + independent carton package + neutral carton + standard export wooden pallets (according to your request) for Ceramic ball.
