608 Ceramic Bearings in material of HIP-Si3N4 Races and Balls+Peek Cage
Description of 608 Ceramic Bearing (HIP-Si3N4 Races and Balls+Peek Cage):
1. HIP-Si3N4 Races and 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. Compared with GPS sintered silicon nitride material, the porosity, wear resistance, crushing value and fatigue contact life of after HIP sintered sinlicon nitride have been greatly improved, which is the preferred material for ultra-high speed and high precision ceramic bearings.
2. PEEK cage: We adopted British Victrex PEEK material, PEEK material 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, and will be fitted to the bearings using our unique design of press-fit double-sided construction.
