The Geislinger Damper is a tuned torsional vibration damper. The steel springs optimize the natural frequency of a system to significantly reduce most of the critical resonances. The tailor-made Geislinger Damper is specifically designed for applications, where high performance, the most compact design, and low cost of ownership is requested. It provides constant stiffness and high damping throughout its service life. The Geislinger Damper is often used in combination with a Geislinger Monitoring System, which enables an early detection of critical loads. The torsional vibration steel spring damper allows for lowest life-cycle cost (LCC).

It reliably protects engine crankshafts, camshafts, intermediate or propeller shafts in all kinds of powertrain applications. By influencing the critical frequency and reducing the torsional amplitudes significantly, the Geislinger Damper can also help to avoid a barred speed range. As modern engines tend to create more than one critical frequency, Geislinger has developed compact dual damper solutions as well as combinations of a Geislinger Damper and a Geislinger VDAMP®. This design flexibility guarantees the best solution for every type of engine and powertrain.

The damper is usually mounted to the free end of the crank- or camshaft and consists of a primary and a secondary section. Between these sections, groups of steel leaf spring packs are arranged. These spring packs, together with intermediate pieces and the secondary section, form chambers which are filled with pressurized engine oil.

The steel springs are tuned to optimize the natural frequency of each individual system. Engine oil is used to reduce torsional vibrations by hydraulic damping. The damper’s elasticity is determined by its shape and number of springs. Thereby, the torsional system is detuned, and the most critical resonance is eliminated. If the outer part vibrates in relation to the inner one, the leaf springs bend, and the pressurized engine oil is pumped from one chamber into another. This reduces the relative motion of the two parts and thus dampens the residual torsional vibrations.

The Geislinger Damper protects your system reliably by reducing engine excited torsional vibrations. The fatigue-resistant steel springs of the Geislinger Damper optimize the natural frequency of the system to eliminate most of the critical resonance. Additionally, the Geislinger Damper enables a highly 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. By supporting state-of-the-art engines, the Geislinger Damper helps to reduce energy costs significantly.
