Novus Gear N-Flex PM Couplings


Specially designed for heavy industrial applications Novus Gear's N-Flex PM range of couplings provides exceptional protection against severe shock loads and vibration.


  • Metal manufacture
  • Mining and mineral processing
  • Pumps
  • Fans
  • Compressors
  • Cranes and hoists
  • Pulp and paper industry
  • General heavy duty industrial applications


  • Severe shock load protection
  • Intrinsically fail safe
  • Maintenance free
  • Vibration control
  • Zero backlash
  • Misalignment capability
  • Low cost


  • Gives protection and avoids failure of the driveline under high transient torques.
  • Ensures continuous operation of the driveline in the unlikely event of rubber failure or damage.
  • With no lubrication or adjustment required resulting in low running costs.
  • Achieves low vibratory loads in the driveline components by selection of optimum stiffness characteristics.
  • Eliminates torque amplifications through pre compression of the rubber elements.
  • Allows axial and radial misalignment between the driving and driven machines.

Construction Details

  • PM Couplings up to PM 40 are made out of special grade of S.G. Iron. Couplings from PM 60 to PM 600 are made of steel casting
  • Separate rubber elements with a choice of grade and hardness, styrene butadiene with 60 shore hardness (Sm60) being the standard.
  • Rubber elements loaded in compression.
  • Rubber elements are totally enclosed.
