ZrO2 Full Ceramic Bearings PTFE PEEK Cage
You are welcomed to come to our factory to buy the latest selling, low price, and high-quality ZrO2 Full Ceramic Bearings PTFE PEEK Cage looks forward to cooperating with you.
ZrO2 Full Ceramic Bearings PTFE PEEK Cage have excellence performance as special electrical and magnetism resistance, wear and corrosion resistance, lubrication 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 were made by full ceramic material:ZrO2, as a standard construction, the cage was made by PTFE, generally we also could make the cage with GFRPA66-25, PEEK, PI, AISI SUS304, SUS316, Cu, etc.
