Severe shock load protection

Gives protection and avoids failure of the driveline under high transient torques

Intrinsically fail safe

Ensures continuous operation of the driveline in the unlikely event of rubber failure or damage

Maintenance free

No lubrication or adjustment required resulting in low running cost.

Vibration control

Achieves low vibratory loads in the driveline components by selection of optimum stiffness characteristics

Zero backlash

Eliminates torque amplification through pre-compression of the rubber elements

Misalignment capability

Allows axial and radial misalignment between the driving and driven machines.

Low cost

The RI Coupling gives the lowest lifetime cost


Construction details

  • Rubber Industrial Couplings up to RI40 are made out of special grade (S.G). Iron. Couplings from RI60 to RI600 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.
