Cerbec® silicon nitride balls outperform traditional all steel bearing balls due to the tailored material properties and finishing that maximize the benefits of using ceramics — making Cerbec balls valuable in applications where steel balls degrade rapidly or where electrical insulation is a necessity. CoorsTek can engineer precision Cerbec® Balls for size ranges from micro-bearings in dental drills to large-application bearings in wind turbines, with a diameter range from 0.5 mm (0.02in) to 50 mm (2in).

New grades in the CoorsTek Cerbec® bearing balls portfolio
- Cerbec SN102 meets the requirements of ASTM F2094 Class I, and is suitable for high-contact stress applications such as machine tool applications
- Currently in development, Cerbec SN103 is suitable for medium contact stress applications such as electric motors and generators. SN103 will meet the requirements of ASTM F2094 Class II
