Product Description
6903 All-ZrO2 Ceramic Bearing Fitted With Cage Of P6/ABEC3 Precision
Description of 6903 All-ZrO2 Ceramic Bearing:
1. ZrO2 races and balls: Races are made by highly purified, sub-micron and after Y2O3-TZP stabled zirconia powder material and are precessed by GPS or HIP 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 6903 All-ZrO2 Ceramic Bearing:
Zirconia bearings have high hareness (1300 HV5) high density (6.09 g/cm3) low thermal conductivity, high fracture toughness KIC:8-11 MPa-m1/2,good electric insulation and excellent chemical stability, resistance to acid and alkali corrosion, its max working temperature can reach 380 ℃.
