Novus Gear N-Flex PCI Couplings


Novus Gear’ N-Flex PCI couplings offer a general purpose, cost effective range, which is manufactured in SG iron for torques up to 60 kN.m.

The Standard Range Comprises

  • Shaft to shaft
  • Shaft to shaft with increased shaft engagement

Applications for Electric Drives only

  • Rubber processing and plastics industry
  • Fluid transmission industry
  • Material Handling
  • Cranes & Hoists
  • Metal manufacture
  • Bulk handling
  • Pulp and paper industry
  • General purpose industrial applications


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


  • Ensuring continuous operation of the drive-line in the unlikely event of rubber damage
  • Achieving low vibratory loads in the drive-line characteristics
  • With no lubrication or adjustment required resulting in low lifetime costs
  • Avoiding failure of the drive-line under short circuit and other transient conditions
  • Allows axial and radial misalignment between the driving and driven machines
  • Eliminates torque amplifications through pre-compression of the rubber elements

Construction Details

  • Spheroidal graphite to BS 1563 Grade 400 / 15
  • Separate rubber elements with a standard SM 80 shore hardness
  • Rubber elements are totally enclosed and loaded in compression
