N-EUPEX DS couplings without fail-safe device allow positive disconnection of input and output side upon failure of the flexible elements due to overload or wear. Then, the metal parts of the DS coupling can freely rotate in opposite directions. 19 sizes offer a wide range of applications. DS couplings are offered in a torque range between 19 and 21,200 Nm. Many types are available ex stock.

Torsion ally flexible and damping pin coupling without fail-safe device

Can be combined with many parts of the N-EUPEX range

Maintenance-free even if used in explosive atmospheres

Can be used in potentially explosive atmospheres; certified acc. to 94/9/EC (ATEX 95)

N-EUPEX DS couplings can be used universally in the whole field of mechanical engineering. They are particularly used in sensitive machines where input and output side are to be disconnected upon failure of the flexible elements or where the coupling must be maintenance-free.
Typical examples of application are:
Pump drives
Compressor drives
Fan and blower drives
