Gesilco® Shaft

Lightweight, maintenance-free shaft solution with integrated flange connection

The Geislinger Gesilco® shaft product range is based on more than 20 years’ experience in developing fibre composite couplings and shafts.

The maintenance-free Gesilco® shaft lines are made of advanced composite material and are characterized by their single-piece manufacturing and their integrated carbon fibre flange connection. The Gesilco® shafts can easily be adapted to the specific requirements of your application. Complete packages with in-house produced steel adapters, bearings, bulkhead seals and additional composite Gesilco® misalignment couplings are available. Their outstanding shock capabilities and good acoustic attenuation further underline the use of Geislinger shafts for high-speed vessels.


Geislinger Gesilco® shafts are produced in one piece, meaning that the flange is not additionally linked to the shaft but is already a part of it. This unique design reduces the weight by approximately 50%. Due to its modular concept, the Gesilco® shaft can be adjusted and tailored to applications depending on their specific requirements especially in terms of transmitted power, length, bending stiffness and torsional stiffness. The stiffness levels of the shafts can be adjusted by altering the angles of the carbon fibre filament windings.

The Gesilco® shafts can measure up to 10 meters in length. The lightweight shaft-lines show high chemical resistance and superior stability throughout their lifetimes.

From designing and manufacturing to calculating the rotation properties of the Gesilco® shaft lines, the entire production is carried out in an in-house process which ensures high quality products and solutions.
