Special Zirconia Ceramic Bearings Of Non-Standard 608
Description :
1. Special ZrO2 Races: Special powder recipe, this kind of zirconia races possesses black color and higher wear resistance.
2. HIP-Si3N4 Balls: Are made of highly purified, submicron silicon nitride powder with an alpha phase of more than 92%, and is processed by GPS (Gas Pressure) sintering and HIP (Hot Isostatic Pressure) sintering technology. So the porosity is highly declined and the wear resistance, crushing value and fatigue contact life of after HIP sintered sinlicon nitride have been greatly improved.
3. PEEK cage: Has similar corrosion resistance to ceramic materials, and has a good resistance to radiation, self-lubricating properties, a high degree of wear resistance and other characteristics. The peek cages are injection molded at high temperature, so have high strength, light body.
