Curved Jaw Couplings

Quick Facts
- Zero backlash, flexible shaft
- Absorbs vibration, angular and parallel misalignment
- Provides electrical isolation
- Identical clockwise and counterclockwise rotation
- Select up to three spider hardnesses
- Multiple bore and shaft connecting configurations
Product Overview
Composed of two metallic hubs with an elastomer insert commonly referred to as a “spider.” The spider material is designed to dampen vibration and to provide electrical isolation. Curved jaw couplings accommodate misalignment and provide an economical solution for motion applications that are continuous or light to moderate in cycle duty.
