6001 All Ceramic Ball Bearings In Material Of ZrO2 or Si3N4 or SSiC
Description of 6001 All Ceramic Ball Bearing:
1. HIP-ZrO2 races and balls are made by highly purified, sub-micron powder material and are processed by HIP (Hot Isostatic Pressure) sintering technology, which can highly improve the properties of material and decline the porosity of blanks. Zirconia bearing has a density and linear expansion coefficient close to that of metal steel shafts, high hardness and high wear resistance.
2. HIP-Si3N4 races and balls are made of highly purified, submicron silicon nitride powder and are processed HIP (Hot Isostatic Pressure) sintering technology too. which can highly improve the properties of material and decline the porosity of blanks.Silicon nitride bearings have high hardness, are wear-resistant, resistant to a variety of strong acid, strong alkali, salt corrosion (in addition to hydrofluoric acid, nitric acid), non-magnetic, non-conductive, high insulation.
3. SSiC races and balls are made of highly purified, sub-micron silicon carbide material, silicon carbide can resist corrosion by hydrofluoric acid, is the most excellent ceramic material with the best corrosion resistance among the known materials.Silicon carbide bearings have a density and coefficient of linear expansion close to that of silicon nitride ceramic materials.
4. Cage and seals: The material of cage can be chosen among PEEK,Teflon and Nylon, the material of seals can be chosen among PEEK, Teflon, Rubbers and stainless steel. PEEK and Teflon material has similar corrosion resistance to ceramic materials, and has a good resistance to many kinds of acid and alkali corrosion.
