Ceramic Bearing Anti - High Temperatures And Corrosive Alumina Zirconia Ceramic Roller Bearings
Full Ceramic Bearings have races and balls that are made entirely of ceramic material and are superior to common steel bearings in many ways. Ceramic is the perfect material for any application seeking to achieve higher RPM’s, reduce overall weight or for extremely harsh environments where high temperatures and corrosive substances are present.
Full Ceramic Bearings are usually made of following materials:
· Silicon Nitride (SiN4)
· Alumina Oxide (Al2O3)
· Zirconia Oxide (ZrO2)
· Silicon Carbide (SiC)
Because ceramic is a glass like surface it has an extremely low coefficient of friction and is ideal for applications seeking to reduce friction.
Full Ceramic Bearing Benefits
· Will not corrode or rust
· 2/3 the weight of steel
· Resistant to resist acids, alkali, blood, salt and water
· Extremely low coefficient of friction and thermal expansion
· Lower friction results in less energy consumed
· Operating Temperature from as low as (-85°C) up to (+ 1750°C)
Full Ceramic Bearing Applications:
Full Ceramic bearings are used in specialty applications like chemical baths, vacuum environments, semiconductor manufacturing, food processing industries and more. Any extreme environment that requires non-corrosive, non-conductive or non-magnetic bearings is ideal for full ceramic bearings.
Ceramic Parameter
Ceramic material composition:
· 95%--99.99% Alumina (Al2O3) · Silicon Carbide · Silicon Nitride
· TTZ: Magnesia partially stabilized Zirconia (ZrO2)
· YTZP: Yttria partially stabilized Zirconia (ZrO2)
· ZDY: Yttria fully stabilized Zirconia (ZrO2)
...
The properties of ceramic:
·Excellent physical & chemical stability ·High temperature resistance
·Excellent wear & pressure & corrosion& insulation resistance and thermal conductivity...
