6207 Ceramic Silicon Carbide Ball Bearings 35x72x17mm
6207 Ceramic Bearing Of SSiC Races And Balls+ Cage With High Precision
Description of 6207 Ceramic Bearing:
1. SSiC races and balls: Are made of highly purified, sub-micron silicon carbide material, can resist corrosion by hydrofluoric acid, which is the most excellent ceramic material with the best corrosion resistance among the known materials.
2. cage: is made of tetrafluoroethylene polymerization of polymer compounds, with excellent chemical stability, corrosion resistance (is one of the best corrosion resistance materials in the world today, in addition to molten metal sodium and liquid fluorine, the ability of all other chemicals, boiling in aqua aqua can not change, Widely used in all kinds of acid and alkali resistance and organic solvent), sealing, high lubrication, non-viscosity, electrical insulation and good anti-aging endurance, excellent temperature resistance (can work in +250℃ to -180℃ temperature for a long time). So the cage and seals of this material fitted in bearings can be used in many special working condition.
