ROBA® DS (steel):

High power density
100% nominal torque even with alternating load
Wear- and maintenance-free

In the ROBA® DS, several FEM-optimized disk packs are used as flexible elements, which are alternately bolted to the input and output sides. It is an extremely robust high performance coupling which - like all shaft couplings made by mayr® - is absolutely backlash-free and at the same time features high torsional rigidity.

As our most versatile shaft coupling, the ROBA® DS is available with various hubs, sleeves, in different design variants and application-optimized designs, e.g. the torque-measuring ROBA® drive-checker®, the ROBA® DS for torque transducers or the easy-to-install ROBA® DS heavy-duty version.
