White Alumina Bearings Circulation Pump or Shield Pump Components Wear Resistance

Dimensions: ODφ18-22mm with holes

IDφ8-12mm

Height 10-15mm

Material: Ceramic is a non-metallic, inorganic, temperature- resistant material that is at least 30% crystalline and is difficult or impossible to dissolve in water. As demands for ceramics performance are higher, the recipe for 95% alumina is also changed and improved so as to improve its friction resistance property, which makes circulating pumps last longer time.

Color: white or brown

Application:

Alumina based ceramics are the most widely used , especially in pump industry due to the excellent combination of different properties, Suzhou Jingci has been in the technical ceramics industry for nearly 20 years and thoroughly familiar with the behavior and characteristics of alumina and zirconium ceramic products, and has been a qualified supplier for manufacturers 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.

Advantages of Ceramic Bearings

1. Low density - Density of 95% alumina ceramics is about 3.7g/cm^3
2. Extremely hard – The Vickers Hardness of 95% alumina ceramics is about 18Gpa,
3. Outstanding surface finish – The roughness of alumina ceramics usually less than 0.25um,
4. Non-magnetic &electrical insulator
5. Striking thermal properties
6. Pretty good corrosion resistance – The alumina ceramics are non-corrosive and won’t be corroded like metal bearings in alkali or acid conditions
