Silicon Nitride Balls

Silicon nitride balls are ceramic balls that are suitable for applications where high loads, high speeds and extreme temperatures are factors. Long life and the need for no lubrication makes this material very suitable for many applications. Silicon Nitride is anti-magnetic and resistant to corrosion by most substances.
