Price Guide: POA


  • Flywheel to shaft
  • Shaft to shaft
  • Flange to flange
  • Flywheel to shaft * stiffness
  • Shaft to shaft * stiffness


  • Marine propulsion
  • High power generator sets
  • Reciprocating compressors


  • Intrinsically fail safe
  • Control of resonant torsional vibration
  • Maintenance free
  • Severe shock load protection
  • Misalignment capability
  • Zero backlash
  • Noise attenuation


  • Ensuring continuous operation of the driveline in the unlikely event of rubber damage.
  • Achieving low vibratory loads in the driveline components by selection of optimum stiffness characteristics.
  • With no lubrication or adjustment required resulting in low running costs.
  • Avoiding failure of the driveline under short circuit and other transient conditions.
  • 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.


  • The driving member is manufactured in steel to BS3100 Grade BT2
  • The inner member is manufactured in steel to BS3100 Grade A6
  • The driving flange is manufactured in steel to BS3100 Grade A3
  • Rubber elements can be fitted and removed without moving the driving or driven machine


Spanish F100 frigate fitted with 4 off Renold Hi-Tec MSC 12.5 half stiffnes couplings between the Bazan MTU diesel engine and the alternator on the generator sets and 2 off Renold Hi-Tec 848.0 DCB cardan shaft couplings between the Bazan Bravo diesel engine and the gearbox on the main propulsion.
