Especially in narrow spaces, couplings can only be inspected visually, because the coupling is hardly accessible with conventional measuring devices. Atypical operation noise or vibrations are generally the first signals that there is something wrong with the coupling.

Couplings are not the most critical part of plants but they have to meet continuously changing requirements. Being reliable, efficient and robust is no longer enough – they should be easy to maintain in order to reduce costs and to avoid downtime. So for choosing the right coupling its characteristics in regard to maintenance and repair are playing a more important role.

Couplings in drive lines are of particular importance because they transmit power between the input and output side, and compensate for inevitably occurring misalignments of the units. Like other machinery elements, couplings need to be serviced at regular intervals. Only if the coupling is optimally tailored to the requirements of the operating conditions and subject to regular maintenance, can it contribute to ensuring the operating reliability and efficiency of a machine or plant.
