Oldham Couplings

Quick Facts

  • Zero backlash, flexible shaft
  • Accommodates high parallel and angular misalignment
  • High torsional stiffness and response
  • Simple configuration, easy to assemble
  • Multiple bore and shaft connecting configurations

Product Overview

Three-piece design composed of two metallic hubs and a center disc made of thermoplastic elastomer. The disc is press-fitted to eliminate backlash and may also serve as a mechanical fuse. The disc slides to accommodate a fair amount of parallel misalignment. Oldham couplings also provide electrical isolation and offer an economical solution for a number of motion applications.
