full ceramic bearing of Silicon nitride materia

full ceramic bearing of Silicon nitride materia Full ceramic bearing made with Si3N4 have excellent performance as special electrical and magnetism,wear and corrsion resistance,lubrication and maintance free when working,especiall high and low-temperature application,etc.,could be used in awful environment and specially condition,The rings and balls: full ceramic materia:Si3N4,The cage :PTFE, GFRPA66-25,PEEK,Phonemic Textiles Tube,etc.Compares than the material ZrO2,the Si3N4 ceramics bearings could endure heavier load and could be used in high tempereature enviroment,Also we could offer precision ceramic bearing which generally used in high-speed and high-rigidity spindle,the manufactuered clearance could be P4to UP grade.
