High-wear-resistance bearing sleeve and preparation technology thereof

The invention discloses a high-wear-resistance bearing sleeve and a preparation technology thereof. The chemical compositions of the high-wear-resistance bearing sleeve comprise C, Si, Mn, Ni, Cr, Nb, Mo, v, Cu, composite rare earth and the balance Fe. The preparation technology comprises: putting high-wear bearing sleeve raw materials, in other words, the chemical compositions of the high-wear bearing sleeve into a container, starting a stirring device to slowly fully stir for uniform mixing for usage, then successively performing mold forming, a process of rough turning, stabilizing and precise turning, a process of rough grinding, a process of milling and turning, and a process of precise grinding and shaping, so as to obtain a bearing sleeve finished product. The bearing sleeve is good in wear resistance, high in strength and precise in dimension, and the preparation technology is simple, convenient to operate, low in cost and high in efficiency.
