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.
