High Speed SSiC Zr02 Ceramic Bearings Thrust 51103
Ceramic Thrust Bearings 51103 Of SSiC Races And Balls+PTFE Cage
Description of Ceramic Thrust Bearing 51103 (SSiC races and balls+ cage):
1. SSiC races and balls: Are made of highly purified, sub-micron silicon carbide material and are sintered by pressureless sintering method, so the free silicon and free carbon in the products are close to the theoretical values.
2. cage: has excellent chemical stability, good corrosion resistance and high temp resistance (resistant to molten metal sodium and liquid fluorine, all kinds of acid and alkali and organic solvent, and can work in +250℃ to -180℃ temperature for a long time)
Performance advantages of Ceramic Thrust Bearing 51103 (SSiC races and balls+ cage):
With a density and coefficient of linear expansion close to that of silicon nitride ceramic materials, high hardness and good wear resistance, resistance to various strong acids, strong alkalis, salt corrosion, high temperature resistance.
