A complete curved jaw coupling is comprised of two hubs and a spider. The three pieced design is easy to assemble.
The curved jaw design incorporates both radial and axial curvature (crowning) to the elastomer (spider). Fail safe design due to the jaw in compression design(continues to function after the elastomer fails).
