Cerbec® Silicon Nitride Bearing Elements

The Cerbec® Difference

CoorsTek develops and manufactures high-performance Cerbec® ceramic bearing elements including bearing balls, roller blanks, and custom components. Hybrid and all-ceramic bearings that use Cerbec improve operation and extend service life for severe-service applications in energy, automotive, aerospace, and a wide range of machinery & equipment applications.


Why choose Cerbec bearing components?

Ceramic bearing balls are ideal to replace steel in applications which demand superior performance in harsh conditions. Cerbec materials are lighter, stiffer, smoother, harder, corrosion resistant, and require less lubrication. Durable Cerbec bearing components also perform well in extreme temperatures and deliver a longer service life.

  • Lower total operating cost
  • Smoother surface & better geometry
  • Harder & stiffer than alloys          
  • Thermal stability & low CTE
  • Corrosion & electrical resistance
  • Lighter weight – low inertia & friction


What are Cerbec bearing components made of?

CoorsTek has engineered advanced ceramics specifically for bearing applications. Cerbec bearing components use proprietary CoorsTek silicon nitride compounds — delivering the ultimate combination of durable mechanical strength, thermal stability, corrosion resistance, dielectric properties, and value for hybrid and all-ceramic bearings. Multiple grades are available to provide the best value for your application.
