The invention discloses a split type bearing saddle for a wagon bogie. The bearing saddle is installed in a side frame guiding frame and comprises a top, a saddle part, longitudinal stop parts and transverse stop parts, detachable wearing plates connected through round pins are arranged on the faces, matched with a side frame, of the transverse stop parts, transverse locating grooves are formed in the middles, in the side frame matching direction, of the transverse stop parts, and transverse stop part round pin installation through holes are formed in the vertical direction. The wearing plates are of T-shaped structures, feet of the T-shaped structures are provided with wearing plate round pin installation through holes, the T-shaped feet of the wearing plates are fixedly embedded into the locating grooves through the round pins, and the wearing plates are made of high polymer wear-resisting nylon materials. According to the split type bearing saddle, the wearing plate and transverse stop part split structure is simple in structure, the characters of the materials and the structure are sufficiently used, all the functions of a traditional bearing saddle can be guaranteed, and when the bearing saddle is worn, the whole saddle can not be scrapped due to the fact that only a worn part is replaced and repaired. Meanwhile, the service life of the wearing plates can be prolonged as far as possible.
