Poona(Holset) Rubber In Compression

Poona (Holset) rubber in Compression couplings are perfect for applications where server shock loads, torsional vibration or variable speed & load applications.

Two basic version allow for shaft to shaft connection or standard SAE flywheel connection.

  • Intrinsically fail safe.
  • Control of torsional vibration
  • Maintenance free
  • Shock load protection
  • Zero backlash
  • Low cost

Applications

  • Diesel driven pumps
  • Pumps
  • Variable speed drive applications.
  • Generator sets
  • SAG/Ball Mill drives

Fire Pump Applications

Note: Poona couplings are an intrinsically fail safe coupling, making them ideal for electric motor or diesel driven fire pumps. In the unlikely event of rubber element failure, the coupling will continue to drive the pump.

RB Series:

  • Ensures continuous operation of the driveline in the unlikely event of rubber damage
  • Achieves low vibratory loads in the driveline components by selection of optimum stiffness characteristics.
  • With no lubrication or adjustment required, results in low running costs.
  • Avoids failure of the driveline 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 rubber elements. The RB Coupling gives the lowest lifetime cost.
