Series 54RDG couplings are reduced diameter gear and grid replacement couplings. Applications include any situation where the overall shaft to shaft separation is minimal. The center member of the 54RDG is split axially, which permits maintenance of the couplings without moving the hubs or connected equipment. The center member is piloted into the adapter providing high speed potential at high torque capacity. When specified series 54RDG couplings can meet requirements of API610 or API671.
