Application of Ceramic Balls :
Ceramic ball can be used in all bearings with special requirement, metering ball , valve ball, track ball, and precision grinding ball; it can be used in fields requiring chemical resistance, high temperature, electronic insulation, magnetic insulation, non-lubrication. It is an idea substitute for steel ball in chemical corrosion application.
