MONOLASTIC® type with 3 holes

0 - 400 Nm / one-piece, flexible flange coupling

The flange coupling MONOLASTIC as a type with 3 holes is a one-piece, flexible coupling with torque-to-bore volume ratio for the drive of diesel engine and hydraulic pumps.

The steel hub with internal spline already pre-assembled allows for axial plug-in connection with the pump shaft. This flange coupling uses flange fastening via 3 holes and is available for all common SAE and DIN pump spline shafts.

The elastomer enables high radial and angular displacements. With this type the flange coupling does not need any centering step on the engine flywheel.

The coupling is centered by the fastening screws only.


  • one-piece, torsionally flexible flange coupling
  • for the drive in diesel engine/hydraulic pump up to 250 kW
  • available in different kinds of Shore hardness (65 und 70 ShA)
  • axial plug-in in combination with pump spline shaft
  • available for SAE and DIN pump spline shafts
