RATO S

Rigidly Mounted Engine - RATO S

Torque range
12,5 kNm - 800,0 kNm

Areas of application
Flexibly mounted engines, rigidly mounted engines.

The highly-flexible RATO S and RATO S+ couplings are torsionally flexible rubber couplings 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 essential parts of the coupling are: the torsional flexible element, the membrane package to absorb the axial and angular displacements and the connecting parts to the drive and driven machinery.

Product benefits

  • Easy and quick installation of the coupling thanks to the segmented design with reduced weights of the individual segments
  • The segments are arranged for maximum thermal load and therefore long service life of the system
  • Compact design with an internal hub for space-conserving and weightsaving drive dimensions in order to cut down on the project costs
  • With the introduction of the ACOTEC range, smaller sizes with higher power density provide good price/performance ratio.
