tional radial and/or axial forces (.. gear wheels, belt pulleys, disk flywheels, hydraulic couplings) are to be used, these must

be agreed by contract. Couplings with peripheral velocities on the outer diameter of up to 3 / must be statically

balanced. Couplings with peripheral velocities over 3 / mustbe dynamically balanced. For maintenance and operation of the couplings, refer to

the specific operating instructions for the coupling. When installing the drives, make absolutely certain that the individual components are accurately

aligned in relation to each other . Inadmissibly large errors in the alignment of the shaft ends to be connected due to angular and axial misalignments result in premature wear and material damage. Insufficiently rigid base frames or sub-structures can also during operationcause radial or axial misalignment, which cannnot be measured when the unit is at standstill. Note: For permissible alignment errors in the case of couplings supplied by FLENDER, please refer to the operating manuals for the couplings.If you use couplings by other manufacturers, ask which alignment errors arepermissible, stating the radial loads occurring. Note: The smaller the radial and angular misalignment between coupling parts on the shaft ends to be connected, the longer the service life and the higher the reliability of theequipment and the quieter the operation. Misalignments of the coupling parts in relation to each other can be caused by inaccurate alignment during assembly, but also by actual operation of the equipment (expansion due to heat, shaft deflection, insufficiently rigid machine frames, etc.).Caution!

This can be done by means of ruler (radial misalignment) and feeler gauge (angular misalignment), as shown
