608 Full Ceramic Bearing Silicon Nitride Ceramic Ball Bearings 8x22x7mm
HIP-Si3N4 Ceramic Bearing 608 Fitted With Peek Cage Of High Precision
Description of HIP-Si3N4 Ceramic Bearing 608:
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 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: 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.
