The RATO R serie is manufactured Vulkan Drive Tech, and is a compensating coupling with torque output ranging from 12.50 kNm to 270.00 kNm. It is also especially intended for use in installations requiring a high level of torsional flexibility and misalignment capacity. The unit has a high dynamic load capacity and good rotational dynamic properties due to the low rotating inertia. There is a good tuning of the systems´s torsional vibration characteristics which is possible due to different torsional stiffness and element configurations available. There is an outstanding noise attenuation characteristics by preventing direct metal to metal contacts between coupling parts. It is typically applied in Oil & Gas applications, which primarily within diesel engine or electric motor driven compressor.
