N-EUPEX DS couplings do not have a fail-safe device, allowing positive disconnection of the input and output side upon failure of the flexible elements due to overload or wear. Then, the metal parts of the DS coupling can rotate freely in opposite directions.
Original FLENDER elastomers ensure the optimal operation of your system. The flexible elements in the N-EUPEX DS series are subject to compression and bending forces. If the flexible elements are irreparably damaged, the metal parts turn against one another without contact, and the power transmission is separated. Fitting new flexible elements will make the coupling usable once more.
