  • Intrinsically fail safe
  • Control of resonant torsional
  • Achieving low vibratory loads driveline components
  • Severe shock load protection
  • Maintenance free
  • Misalignment capability
  • Zero backlash
  • Noise attenuation


  • Ensuring continuous operation of the driveline in the unlikely event of rubber damage vibration by selection of optimum stiffness characteristics.
  • Achieving low vibratory loads in the driveline components by selection of optimum stiffness characteristics.
  • Avoiding failure of the driveline under short circuit and other transient conditions.
  • With no lubrication or adjustment required resulting in low running costs.
  • Allows axial and radial misalignment between the driving and driven machines.
  • Eliminating torque amplifications through pre-compression of the rubber elements.
  • Giving quiet running conditions in sensitive applications by the elimination of metal to metal contact.


  • Available options are: Series 6, Series 8, Series 10, Series 16
  • 2,3,4 or 5 rubber elements per cavity are available. Rubber elements up to 15" diameter are manufactured
