Ball Bearing Ceramic Ball

Ceramic (silicon nitride) balls feature highly controlled and consistent geometry as well as an exceptionally smooth and uniform surface finish. Compared to steel, the material's lighter weight, higher stiffness, and inert properties facilitate higher operating speeds, extended bearing life, and expanded design possibilities for unique and demanding bearing applications.

Properties	Improvement In Bearing Performance
Lower internal friction	Lower internal temperature Reduced cage and raceway wear
Lighter weight: 58% lighter than steel	Lighter overall bearing weight Decreased centrifugal force Decreased gyroscopic movement
Higher stiffness & higher hardness: 68% stiffer than steel	Reduced skidding Less friction Lower operating temperatures Less wear
Smoother surface: 75% smoother than steel	Decreased lube degradation No cold welding/adhesive wear Less friction Lower operating temperatures Less wear
Corrosion resistance	Durability in harsh environments Less wear Resists galling
Higher maximum temperature than steel:  +1000°C	Wider operating range
Lower thermal expansion	Lower operating temperatures
