Jaw Coupling

RYDON jaw couplings are characterized by small dimensions, low weight and low mass moments of inertia yet transmit high torques. Running quality and service life of the coupling are improved by accurate all-over machining. Their application is ideal for transmitting torque while damping torsional vibrations and absorbing shocks produced by the uneven operation of certain prime movers.


In contrast to other flexible couplings, the intermediate members of which are subject to bending stress and are therefore prone to earlier wear, the flexible teeth of RYDON jaw couplings are subject to pressure only.


  • Urethane spiders provide high abrasion resistance and elasticity, along with good damping characteristics
  • The spiders are offered in a variety of shore hardnesses, each providing a different level of torque capacity, damping and chemical resistance
  • The standard curved jaw spider design has a hole in the center to accommodate small between shaft end measurements
  • The spiders have a temperature capacity of 212įF
  • The curved jaw spiderís urethane material also resists oil, dirt, sand, grease, moisture, many solvents as well as atmospheric effects of ozone.
