CoorsTek can engineer precision Cerbec® Balls with a diameter range of .5 mm to 50 mm. You will find them in applications that range from micro bearings in dental drills to large wind turbines.

Cerbec® silicon nitride balls outperform steel balls due to the material properties and finishing that maximize the benefits of using ceramics. These attributes are valuable in applications where steel balls degrade rapidly or where electrical insulation is a necessity.

Material

Cerbec® balls are manufactured out of CoorsTek silicon nitride. This tough ceramic material has unique properties that outperform traditional steel alloys

  • 58% lighter then steel
  • 121% harder
  • 68% stiffer
  • 76% lower thermal expansion
  • Electrically resistant
  • Corrosion resistant

Finish

They produce balls with exceptionally tight tolerances and smooth surfaces. This allows them to improve overall performance.

  • Decreased friction
  • Lower lubrication required
  • Reduced wear
  • Elimination of vibration

The combination of superior material and finish deliver better overall service life, reduced operating costs, higher reliability and longer part life than traditional steel balls.
