We are leading suppliers of Samiflex Elastic Coupling. Samiflex couplings are available in conjunction with Spacers (single/double), Brake Wheel, Disc, Flywheel & Floating coupling configurations. Supplied for use with Taper Bushes/QD bushes, also.


Apart from standard hubs of GG-25, Ductile Iron (GGG40), Cast Steel (GS45), Stainless Steel (AISI 316), high resistance aluminum alloy (C135) high-performance polyurethane, shock-resistant polyamide and carbon fibre composites can also be designed, to suit specific requirements.

There are only tour parts to SAMIFLEX couplings. The two identical hubs (1) and (2) are made from high-strength cast iron, ductile iron, cast steel or aluminium alloy, each with eight teeth, (except for the A0d A00, which have six and four respectively). The elastic insert, which is made from a special polyurethane elastomer, fits between the hubs. The outer retaining ring is made of steel or polyamide, with interior pins for adjusting this ring on the elastic insert. The ring also has two threaded holes, symmetrical to each other, through which two set screws can be fitted. The set screws are aligned to a mating holes in the elastic insert and once secured ensures that the ring can not move during operation

Assembly and Disassembly:

  • After machining the bores, the hubs (1) and (2) are fitted onto the shafts. 
  • Note, the retaining ring should be located over the shaft prior to setting the DBSE (Distance Between Shaft Ends) and aligning. 
  • The teeth of the hubs are positioned facing each other, to the correct gap (E). The elastic insert (3) can then be installed in the slots formed by the parallel teeth. 
  • When the insert is in position, slide the ring (4) onto the polyurethane insert, tapping gently into place with soft-headed hammer , until the ring's inner pin falls into place in center hole of insert. Centrifugal force will expand the elastic insert to fix it tightly to the inside of the ring. 
  • If the alignment cannot be kept within the admissible tolerance, the ring can be secured using locking set screws (fig. 3). 
  • To disassemble, remove the ring. The insert can then be quickly and easily removed and replaced. No special tools, screws, bolts or other fasteners are needed. 
  • Samiflex means saving in manpower and downtime, easy of installation economy and long, trouble free service


Features and Benefits:

  • Assembly and disassembly of the elastic insert without having to displace the motor or the unit being driven. this advantage permits the inspection of the insert at any time without a lengthy shut down. simply displace (move to one side) the ring, remove the insert, inspect and if necessary replace with a new one. all this takes a few minutes.
  • The two hubs works independently as the coupling transmits torque. This concept allows free wheeling of the motor or driving unit in the system by simply moving the ring and removing the insert. this is specially helpful when the driving unit is a combustion engine and it becomes necessary to repair or test the engine without any load.
  • As the hubs are independent of each other, if the insert ruptures or breaks, there is no metal to metal contact creating any spark thus enhancing the explosion proof properties of the coupling.
  • The polyurethane insert is a key part of the coupling and is made of a very special elastomer compound. its estimated average lifetime is 25000 hours work under normal conditions.
  • The coupling is easily aligned without expensive tools or measuring devices (see our installation instructions)

AL Rotary Single Joint Couplings is an all-metal coupling between 2 shafts, allowing for radial and axial misalignment and simultaneously transmitting torque, even at variable speeds. These couplings have the ability to transmit power even at high working angles.

This joint was born to Satisfy all the exigency of economy together with a reasonable possibility to transmit torsional couple. Their employment in mainly fit for medium-low speed and with limited torsion moments.
