Alumina ceramic bearings and shafts 95% Alumina Bearing for shield Pump Anti-abrasion
Dimensions: ODφ22*IDφ10*8
Material: Alumina ceramic, or aluminum oxide, Al2O3, is a non-metallic, inorganic engineering material. Ceramic parts are usually made from 95% alumina, 96% alumina, 99% alumina, or even higher percent like 99.5%.
Color: white or brown
Application: the motor of pumps such as micro pump, shield pump, circulating pump, centrifugal pump, impeller pump, magnetic drive pump, ground source heat pump, aquarium pump, fountain pump etc.
Properties of aluminum ceramic bearings
• Minimal thermal expansion
• Excellent thermal shock behavior
• Striking temperature resistance
• Low thermal conductivity
• High corrosion resistance
