Shijiazhuang Zhengshi Science and Technology Corporation has developed a new kind of magnetic prestressed structural bearing and obtained national patent. This bearing consists of two parts. One part is a normal rolling or sliding bearing; the other part is a magnetic prestressing part. Through the precise adjustment of the magnetic prestressing part, the friction resistance of the ordinary rolling or sliding bearing part can be reduced by 95%. (Theoretically, the resistance should be eliminated by more than 95%, and it cannot be ideally achieved due to processing, assembly, and actual use of the environment). High load capacity, operating temperature 200 °C and other advantages. Installation, use, maintenance and disassembly are the same as ordinary bearings.
The method for realizing the above characteristics is to adopt the concept of prestressing, to use magnetic same-sex repulsion, and the principle of opposite-phase attraction to generate magnetic prestress, so that the vector of load and preload on the bearing is zero, so that the friction on the bearing is zero. Therefore, the bearing's ultra-low friction, ultra-low wear, long life, and ultra-safety are obvious. Can be widely used in cars, high-speed trains and other vehicles. Can also be applied to precision machine tools, machining centers, turbines, generators, aero engines, etc., can be used in a vacuum, wherever there is a common bearing can be used. And energy saving, long life, no heat, no spare parts.
