ROBA® DS (servo): Compact, torsionally rigid, backlash-free shaft coupling

Aluminium version
100% nominal torque even with alternating load
Wear- and maintenance-free

ROBA-DS couplings are shaft connectors and transmit torques torsionally rigidly and backlash-free. At the same time, they compensate for angular misalignments and axial displacements on single-jointed couplings (Type 950._ _ _), and additionally for radial misalignments on
double-jointed couplings (Type 951._ _ _).
