Cerbec® Ceramic 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.
