Gesilco D

The Geislinger Gesilco D is a steel‑spring damping coupling with an oil damper chamber, used on marine propulsion shafts to absorb torsional vibrations and protect downstream gearboxes. The supplied category identifies the equipment as Flexible Coupling, and it is normally installed in the propulsion train between the prime mover, gearbox and propeller or within the stern-tube and propulsor arrangement. In that listed role, its primary purpose is to transmit torque, support the shaft, seal the hull penetration or control propeller thrust according to the listed component. Shafts, bearings, seals, couplings, CPP mechanisms and shaft generators perform different roles, so alignment, lubrication and wear limits remain component-specific. The model designation identifies the listed configuration, but no additional performance, approval or construction detail is inferred from the model code beyond the information supplied in the source record. The source metadata also states capacity: 20000 kW. For exact ratings, dimensions, settings, capacities, materials and variant-specific limits, refer to the manufacturer documentation for the exact figure.
