The Geislinger Coupling protects your system reliably by reducing engine excited torsional vibrations. The fatigue-resistant steel springs of the Geislinger Coupling optimize the natural frequency of the system to eliminate most of the critical resonance. Additionally, the Geislinger Coupling enables a more compact design of the whole propulsion system. This reduction in total weight leads to a better efficiency along with less loaded components and consequently longer operating times between service intervals. Supporting state-of-the-art engines, the Geislinger Coupling helps to reduce energy costs significantly.
