The PYI Flexible Shaft Coupling reduces vibration from engine and transmission, compensates for minor misalignments, and isolates the shaft while absorbing shock loads.

  • Ideal for marine engine installations
  • Polyurethane flange creates a flexible barrier to reduce drive train noise and vibration to quiet your drive train
  • Absorbs transmission shock loads caused by the propeller and high speed gear changes
  • Fail safe design, both forward and reverse thrust is taken in compression from the steel straps, giving a durable design even in extreme conditions
  • The polyurethane disc is backed up by two metal compression straps, one on either side of the flexible coupling. These metal straps hold the system in constant compression, whether the drive train is in forward or reverse. This feature extends the life of the system dramatically.

    The R & D Flexible Coupling will also absorb shock loads, resulting from gear changes or the propeller striking a submerged object. The polyurethane disk will distort with light shock loads and is designed to be sacrificial in the event of severe shock load, saving on expensive drive train repairs. If the disc is destroyed from massive shock load, the metal compression straps keep the coupling intact, ensuring that the drive system is functional in both forward and reverse.
