The utility model relates to a hanging pulley for a sliding door. The hanging pulley for the sliding door still comprises a track pulley. A connection bottom plate arranged on the lower end of a pulley seat is connected with the sliding door via a mounting screw in a linked way. The utility model is characterized in that the both sides of a shaft line of the track pulley on the pulley seat are respectively provided with more than two pairs of rolling truckles of track side surfaces. The track pulley and a rolling plane of the truckle are perpendicular to each other, and the periphery of the truckle, compared with the side surface of the track pulley, is closer to a side wall of a track. The hanging pulley for the sliding door with the structural characteristics causes the track pulley not to be clamped tightly at the time of operation by that a plurality of pairs of truckles which are arranged on the side surface of the track are regulated and slid, and in addition, a plurality of truckles are arranged corresponding to the both ends of the track pulley, and the structural arrangement is rational. The utility model can realize a most stable sliding effect.
