6902 Ce Of ZrO2 Races And Balls + Cage Of P6/ABEC3 Precision
Description of 6902Ce :
1. ZrO2 races and balls: Races are made by highly purified, sub-micron and after Y2O3 partially stabled zirconia powder material and are precessed by GPS sintering technology.
2. cage: 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 advantages of 6902Ce:
Zirconia bearings have high hardness, wear resistance, resistance to various corrosion. For reference, the load of 6902 Ce is 3225 N (Cr) and 2250N (Cor) and its max operating speed can reach 26000 rpm with grease lubrication and 34100 rpm with oil lubrication.
| ►Key properties of zirconia |
