Zusammenfassung:	The utility model discloses a four-row cylindrical roller bearing dismounting lifting appliance, which comprises a bearing chamber, a bearing and a cylindrical roller, the inner wall of the bearing chamber is movably connected with the surface of the bearing, and the inner wall of the bearing is movably connected with the surface of the cylindrical roller. Through cooperative use of the bearing chamber, the bearing, the cylindrical roller, the protection assembly, the clamping block, the protection plate and the connecting screw hole, the supporting positioning sleeve slides into the inner wall of the clamping block, so that the supporting plate is located at the top of the clamping block, and after the connecting groove is flush with the connecting screw hole, a user can insert the connecting rod into the connecting groove and the connecting screw hole; the problems that in the prior art, objective outer ring oval deformation exists after most four-row cylindrical roller bearings are used, meanwhile, frictio
