CoorsTek Introduces Two New Bearing Balls at Hannover Messe 2019

Golden, Colorado, USA ─ CoorsTek, a world’s leading technical ceramics manufacturer, will present the broadest range of application-specific ceramic bearing balls in the market at the Hannover Messe exhibition in Hannover, Germany. The Company will exhibit in Hall 22, Booth A33.

Pyramid of Cerbec® bearing balls."CoorsTek is currently the only supplier of technical ceramics offering the most complete range of silicon nitride materials in the market,” said Andreas Schneider, Executive Vice President, Europe. "Our global manufacturing excellence, combined with our extensive knowledge of ceramics, customization expertise, and technical service make us a true partner to develop high-end materials together with our customers.”

At Hannover Messe, CoorsTek will highlight the following developments:

CoorsTek Cerbec® bearing balls portfolio introduces two new grades
Silicon nitride Cerbec® bearing elements are especially valuable in applications where steel balls degrade rapidly or where electrical insulation is a necessity. CoorsTek Cerbec® balls are manufactured from high-quality silicon nitride and are 58% lighter than steel alloys. The lighter weight lowers centrifugal force, reduces gyroscopic weight, causes less friction, and minimizes ball skidding. CoorsTek completes its silicon nitride bearing balls portfolio by adding the following additional grades:

  • SN102 meets the requirements of ASTM F2094 Class I and is especially suitable for high-contact stress applications such as machine tool and aerospace applications;


  • SN103 is suitable for medium contact stress applications such as electric motors, generators, and e-mobility applications. SN103 meets the requirements of ASTM F2094 Class II.


CoorsTek legacy Cerbec® bearing balls portfolio includes:

  • NBD200, that is especially suitable for small size bearing balls of 3.175 mm diameter and smaller, such as dental drills.


  • SN101C, that is typically used for applications where bearing balls greater than 3.175 mm diameter are required. Applications include bearing balls for wind energy technology.


CoorsTek also showcases advanced silicon nitride ceramics:

  • Advanced silicon nitride ceramics withstand extremely harsh environments with superior performance and outperform traditional steel alloys. This range of silicon nitrides is suitable for a number of industrial applications such as engine components, cutting tools, automotive powertrain, and brake discs, bearing balls and rollers, and other critical parts.


  • Silicon nitride injection molding is ideal for manufacturing high-performance and high-tolerance components. Among the variety of CoorsTek processing options, ceramic injection molding offers a cost-effective technique for the volume production of complex, intricate designs.
