Ceramic ball

Silicon Nitride BallsSilicon Nitride balls are a popular choice for bearing designers and other high precision product

applications Long life makes this material very suitable for aviation applications. 

Silicon Nitride is anti-magnetic and resistant to corrosion by most substances.
