Ceramic ball Saint Gobain Ceramics
Cerbec Si3N4 (MgO)

CERBEC balls are known worldwide for their extremely smooth surface finish. Our manufacturing process is totally dedicated to Si3N4 finishing. This focus yields surface finish typically < 0.10 micro inch (< 0.003 micron) consistently from batch to batch for the tens of millions of balls we produce annually. Reduced bearing friction from Si3N4 is a function of smooth surface finish - it must be done right all at the time. CERBEC balls have over 10 years' history of superior surface finish.
