Geislinger Coupling

The Geislinger Coupling is a torsional elastic high-damping steel spring coupling with hydrodynamic damping properties. High reliability, long intervals between overhauls, and low operating costs are some of the main features of this coupling. The Geislinger coupling is perfectly suited for all types of machinery, but in particular for diesel and gas engines.

The Geislinger Coupling has proven its efficiency and extremly long service life for more than 60 years.

Resistant to heat and oil and equipped with high-grade steel springs, this advanced coupling design provides constant product performance during its entire lifetime.

While steel leaf springs transfer torque and provide elasticity, pressurized oil gives wearless hydrodynamic damping.

Stiffness and damping can be pre-adjusted individually, which makes it possible to shift torsional critical speeds and dampen torsional vibrations.

The Geislinger steel spring coupling can be combined with a Geislinger Flexlink, or with a coupling of our composite Gesilco® product range, in order to cope with higher misalignment requirements. For a better acoustical behavior Geislinger Silenco couplings can be combined with Geislinger steel spring couplings.
