High-Performance Ceramic Balls

Cerbec Silicon Nitride Ceramic Balls

Cerbec® Silicon Nitride Balls

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).

Material

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

  • 58% Lighter
  • 121% Harder
  • 68% Stiffer
  • 76% Lower thermal expansion
  • Electrically resistant
  • Corrosion resistant

Finish

CoorsTek produces ceramic balls with exceptionally tight tolerances and smooth surfaces. The excellent surface finish allows Cerbec® Balls to improve overall performance.  

  • Decreased friction
  • Lower lubrication required
  • Reduced wear
  • Vibration elimination

Service

The combination of superior material and finish deliver better overall service life than traditional steel balls. Additionally, Cerbec® Balls are used in harsh duty applications, including corrosive environments and high operating temperatures that would rapidly degrade steel balls.

  • Reduced operating costs
  • Limited maintenance
  • Higher reliability
  • Longer part life

ZIRCONIA BALLS & BALL BLANKS

Extremely durable CoorsTek zirconia balls are ideal for severe-service environments like oil & gas down-hole, chemical manufacturing, and other high-pressure, high-temperature, and corrosive applications. 

Used as components for valves, check valves, flow control, and flow measurement, zirconia balls are available in many sizes.

ALUMINA BALLS & BALL BLANKS

CoorsTek alumina (aluminum oxide) balls are abrasion resistant, high hardness, and thermally stable at temperatures up to 1800° C — useful in oil & gas down-hole, chemical pump applications, and as part of valves, bearings, flowmeters, and more.
