Highly Flexible Couplings - RATO S+

Torque range
from 180.0 kNm up to 360.0 kNm

Flexibly mounted engines, rigidly mounted engines

The highly-flexible RATO S+ coupling is a torsionally flexible rubber coupling that compensates radial, axial and angular shaft displacements of the connected machinery. The torque is transmitted by elements loaded in shear. The different torsional stiffnesses and damping factors available provide the possibility to satisfactorily tune the torsional vibration behaviour of the drive system. The newly developed ACOTEC series products are characterized by improved performance in the essential technical data.


  • Smaller coupling with high power density ensures lower project costs thanks to a more favourable price-performance ratio
  • Innovative design anticipates enhancements in the power and speed of the engines
  • Reduced mean mass provides significant advantages for the weight of the lightweight construction required
