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.
