stainless steel outer ring Si3N4 ceramic ball PTFE cage hybrid ceramic bearing 6313

all especially silicon nitride ball of mix ceramic ball bearing has low density, high hardness, low coefficient of friction, there is no magnetic electricity,wear-resisting.And rigid self-lubricating characteristics are good, especially suitable for high-speed, high precision and long life of the hybrid ceramic ball bearing roller. Generally enclose and adopt the bearing steel (GCr15) or stainless steel (ALSI 440C, 316,304), the ceramic ball can select ZrO2, Si3N4 or SiC material for using.

Usage:bearings balls for high precision,high speed,vacuum,fixed anode X-ray tube,high temp,low temp,electric insulation,high precision ballscrew set,valve balls for acid,alkali,salt,measure pumps,flowmeter. 

Characterisitic:resistance to strong acid,strong alkali,salt and gas of deleterious, especially resistance to hydrofluoric acid,long life,high hardness,resistance to wear.
