Silicon Nitride (Si3N4) Ceramic Balls are formed from a new material suitable for applications where high loads, high speeds and extreme temeratures are factors. Long life and the need for minimal lubrication make this material appropriate for extreme applications.

 

Silicon Nitirde is non-porous, non-magentic, non corrosive, lighter than steel and, in ball form, is harder than steel. Because ceramic balls are non-porous they are virtually frictionless and are capable of spinning faster than steel balls.

 

 

Characteristics:
1) Density 3.25 g/cm3 (59% lower than steel)
2) Excellent wearability
3) Max working temperature up to +800°C
4) Low coefficient of thermal expansion
5) Very high hardness Hv 1400
6) Nonmagnetic
7) Electrical isolating
8) Self-lubricating
9) Excellenct corrosion resistance

10) Applicable for high speed bearings
