The present invention relates to a ceramic bearing capable of stably operating, and belongs to the technical field of bearings, wherein the bearing can stably operate in a wide temperature range and a wide rotation speed range. With the method of the present invention, under the premise of no change of the structure form, the lubrication way, the sizes of the retainer and other parts of the original bearing, the complex heat control, the high precision retainer design manufacturing, the high performance lubrication agent improving and other complex technical ways are not required, and a small part of the ceramic balls are changed into the steel balls so as to ensure the stable operating of the high speed bearing, reduce the vibration and the noise, reduce the drag torque fluctuation, and improve the product operating stability. According to the bearing using the technology, only the partial rotation bodies is changed, such that the comprehensive performance is equivalent to the original ...
