Compared with steel ball, Si3N4 ball has following advantages: 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, Ra could be 4~6 nm. 7. Can endure high temperature with high hardness and strength up to 1050ºC. 8. Never rust, and can roll without lubrication. 9. More corrosion resistant than steel. 10. Free of metal contamination. 11. Non-magnetic. 12. Electric isolation. 13. No adhesive-wear. All above combination makes Si3N4 to be first choice for bearing ball material.
Apply To: Alumina ball is widely used in Ceramic industry,cement industry, paint industry, Color industry, chemical industry,pharmaceutical industry, coating industry and mining industry. Technical Data
