All Ceramic Bearing 6001 In Material Of Silicon Nitride + With P6/ABEC3 Precision
Description of Ceramic Bearing 6001 (Si3N4+):
1. 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. cage: is commonly known as "plastic king". It is made of tetrafluoroethylene polymerization of polymer compounds, with excellent chemical stability, corrosion resistance (is one of the best corrosion resistance materials in the world today, in addition to molten metal sodium and liquid fluorine, the ability of all other chemicals, boiling in aqua aqua can not change, Widely used in all kinds of acid and alkali resistance and organic solvent), sealing, high lubrication, non-viscosity, electrical insulation and good anti-aging endurance, excellent temperature resistance (can work in +250℃ to -180℃ temperature for a long time). So the cage and seals of this material fitted in bearings can be used in many special working condition.
Performance advantages of Ceramic Bearing 6001 (Si3N4+):
In addition to the many advantages of ZrO2 ceramic bearings, but also has a small volume density, light weight structure, resistance to dry friction, low coefficient of linear expansion, self-lubrication, high fatigue life. They have high hardness Hv1500, 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, high temperature resistance to 800 ℃, high speed, its service life is far beyond the same metal bearings several times to dozens of times, etc.
Application of Ceramic Bearing 6001 (Si3N4+):
Si3N4 ceramic bearings are preferred structure for high-speed, alternating load environment, so are usually use as high-speed spindle, electric spindle, CNC machine tool and motorized spindle bearings.
