Lightweight, maintenance-free shaft solution
Description Tech overview Tech gallery Related products


The Gesilco® shaft lines are made of advanced composite material and are characterized by their one-piece manufacturing with an integrated fibre flange connection. The Gesilco® shafts can easily be adapted to your requirements. Complete packages with steel adapters, bearings, bulkhead seals and Gesilco® composite misalignment couplings are possible. Outstanding shock capabilities and good acoustic attenuation further underline the use of Geislinger shafts for vessels running at high speeds.

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 fiber filament windings.

The Gesilco® shafts can measure up to 12 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 the high quality of Geislinger products and solutions.

The Geislinger Gesilco® product range is based on more than 25 years’ experience in developing fiber composite couplings and shafts. All Gesilco® products are manufactured in our Austrian Geislinger locations.
