Rexnord PKIT SR54RDC 312 STL Disc Pack Hardware Kit

Rexnord PKIT SR54RDC 312 STL Disc Pack Hardware Kit is the factory-recommended hardware kit for the Thomas Series 54RD disc couplings, sized 312. It includes the complete disc-pack hardware and cap screws necessary to assemble one coupling, delivering the components needed to replace a worn or damaged disc pack without sourcing individual parts. The 312 STL designation indicates the coupling size and the steel disc-pack configuration used with this kit, aligning with Rexnord's standard disc-coupling parts for the SR54 family (54RD/54RDG). This kit is intended for installation in mechanical power transmission setups where a compact, flexible coupling is used to transmit torque between shafts while accommodating misalignment and end-float, ensuring proper clamping of the disc pack and hub interface when reassembling the assembly.
