Diameter 4mm Length 20mm Silicon Nitride Pin Rod 

Silicon nitride ceramics have excellent mechanical properties and machinability, high temperature resistance, corrosion resistance, wear resistance, high hardness, adhesion resistance, small friction coefficient and self lubrication. The shafts and sleeves made of silicon nitride ceramics are widely used in ceramic plungers, high-temperature insulating supports, ceramic nozzles, ceramic ball valves, dry pressing medium molds, magnetic pumps, chemical pumps, mortar pumps, plunger pumps, etc; The seal ring can be used for mechanical seal of industrial pump; It is also especially suitable for high-speed, high-temperature, corrosion-resistant, insulated, magnetically isolated, long-term operation that cannot be lubricated regularly.
