The utility model discloses a bearing steel pipe for a rolling bearing ring. The bearing steel pipe is provided with a steel pipe outer body and a steel pipe inner body, the steel pipe outer body covers the outer side of the steel pipe inner body; a buffer layer is arranged between the two; the buffering layer is a regular polygon buffering elastic piece, so that the damping performance of the steel pipe outer body and the steel pipe inner body is greatly improved, high stability performance is achieved, and the regular polygon buffering elastic piece can be tightly attached to the steel pipe outer body and the steel pipe inner body. The overall stability of the bearing steel pipe and the comprehensive performance of the inner side face and the outer side face can be improved; the purposes of oxidation resistance, high temperature resistance, high strength, corrosion resistance and the like are achieved; the service life of the bearing steel pipe is prolonged; the problem that a traditional bearing steel pipe
