The present invention relates to a process for manufacturing an electric steering damping bush. According to the present invention, the process for manufacturing an electric steering damping bush including an inner pipe, a rubber member, an outer pipe and a bearing comprises: a component manufacturing step in which an inner pipe, a rubber member, an outer pipe and a bearing are manufactured; and a component coupling step in which the inner pipe, the rubber member, the outer pipe and the bearing manufactured in the component manufacturing step are integrally formed, wherein a step of manufacturing an inner pipe in the component manufacturing step includes a slitting step in which a pipe having a penetration hole in a center is slitting by a certain length, a press bending step in which an upper end of an outer circumferential face for the pipe is rounded, and a cutting step which performs cutting to form a protrusion on an circumferential face of the other end of the inner pipe after the press bending step. According to the present invention, durability is improved due to added precision, a defect rate decreases, and a process for manufacturing an electric steering damping bush capable of decreasing vibrations and absorbing shock is provided.
