Expounds the spindle bearing with high speed and high precision nitride ceramic roller materials performance characteristics and steel rolling body performance comparison, and ceramic ball bearings at home and abroad market analysis and prospect. bearing manufacturers
By rolling bearing collar, rolling body and keep sensor into. Due to the contractor and rolling body contact with load and rotating by function, thus repeatedly producing contact pressure and deformation. Due to the steel bearing oneself material performance characteristics, bearing the main form of failure is fatigue, spalling fatigue life short, application scope is very limited. And ceramic materials (Si3N4) with low density, medium elastic modulus, thermal expansion coefficient little, high hardness, resistance to high temperature, corrosion resistance, no magnetic advantages to Si3N4 ceramics ball rolling body for the ceramic ball bearings can significantly improve the bearing contact fatigue life, greatly expand the application field of rolling bearing,bearing suppliers has been w idely used in all kinds of high accuracy, high speed machine tool, car, car racing, subway, motor, aviation engine, oil chemical machinery, metallurgy, machinery, etc. At present, si3n4 ceramics ball and ceramic ball bearings have started to enter PiLiangHua production stage, particularly in machine tool with high speed precision spindle bearing and resistance to high temperature corrosion resistant bearing field broad prospect of application.china bearing supplier
