7207 Ceramic Bearing In Material Of ZrO2 Races and Balls+PTFE Cage
Description of 7207 Ceramic Bearing (ZrO2 Races and Balls+PTFE Cage):
ZrO2 races and balls: Are made by highly purified, sub-micron and after Y2O3 partially stabled zirconia powder material, are processed by AP (Atmospheric Pressure) sintering and HIP (Hot Isostatic Pressure) sintering technology, so their properties are highly improved.
PTFEcage: has excellent chemical stability, can resistant to molten metal sodium and liquid fluorine, to all kinds of acid and alkali resistance and organic solvent,can work in +250℃ to -180℃ temperature for a long time.
Performance advantage of 7207 Ceramic Bearing (ZrO2 Races and Balls+PTFE Cage):
ZrO2 material can stand 380℃ working temperature and have high density(6.05-6.09g/cm3), good wear resistance and high hardness (1300 HV5) , besides have excellent chemical stability, resistance to many kinds of strong acid and alkali corrosion.
