Rexnord 591021 162.S54RD Thomas Disc Coupling, 162 size, S54RD type, straight configuration. All-metal flexible disc coupling transmits torque through laminated stainless-steel disc packs while accommodating misalignment. Suitable for industrial power transmission applications requiring high torsional stiffness and zero backlash.

The Rexnord Thomas Series 54RDG couplings are reduced diameter gear and grid replacement couplings. Applications include any situation where the overall shaft-to-shaft spacing is minimal. The center member of the 54RDG is split axially, which permits maintenance of the couplings without moving the hubs or the connected equipment. Center member is piloted into the adapter providing high-speed potential at high-torque density.
