HRGQ superfinish blanks from Toshiba to Grade 5 and keeps stock for a range of gauges from M15 to P15. And we also do non-standard sizes.

Silicon Nitride (Si3N4) has the most versatile combination of mechanical, thermal, and electrical properties of any technical ceramic material. It is a high performance technical ceramic that is extremely hard and has exceptional thermal shock and impact resistance. It surpasses most metals high temperature capabilities and has a superior combination of creep and oxidation resistance. Additionally, its low thermal conductivity and high wear resistance make it an excellent material that can withstand the toughest of conditions in the most demanding industrial applications. Silicon Nitride is an excellent choice when high-temperature and high-load abilities are needed.

Advantage of Silicon Nitride

Most common used in bearing applications, silicon nitride balls have a coefficient of thermal expansion of only 30% of steel balls, which means there is less friction generated in bearings as heat increases. Silicon Nitride balls requires less cooling system as they have low thermal conductivity that reduces the amount of heat absorbed. The temperature operating range for those balls are up to 800C(1470F). With non-corrosive, anti-magnetic and superior wear resistance, they are mostly used in high-endurance and high-temperature applications.
