Full ceramic bearing have excellence performance as special electrical and magnetism resisance,wear and corrosion resistance,lubricaton and maintenance free when working,especially high and low-temperature application.etc.could be used in awful environment and specially condition.The rings and balls made by full ceramic material:Zr02,as a standard constructure,the cage made by PTFE,generally we also could make the cage with GRPA66-25,PEEK,PI,AISI SUS304,SUS316,Cu,etc.
Material POM and PA have excllent mechnical strengh and wearing resistance,is suitable for manufacturing precision plastic bearings.with good self-lubrication performance and iow friction coefcients.Inaddition and speed application.Plastic bearing made with POM is the most extensive sort of all the plastic bearings.Generally the inner and outer rings made with POM or PA,Cage made with PA and the balls made with glass,stainless or ceramic.These bearings could be used in some al kali environment but nut proper to some acid environment.
