Geislinger unveils lighter acoustic coupling

The ultra-lightweight coupling has been designed to reduce stiffness and mass while enabling more precise eigenfrequency tuning. Geislinger said the design is intended to improve vibration, noise and harshness (NVH) performance while simplifying assembly and installation.

“With the SILENCO® Neo Acoustic Coupling, we continue to push the boundaries of innovative coupling technology,” said Torsten Philipp, chief executive of Geislinger.

“By significantly reducing the weight of the SILENCO® coupling by 30%, Geislinger has not only created the most lightweight NVH coupling on the marine market but also demonstrates that superior noise reduction and weight-saving design can go hand in hand.”

The SILENCO® Neo is designed to reduce structure-borne sound transmission between engines and connected drivetrain components. Its dynamic stiffness characteristics are intended to support engine vibration isolation, reduce foundation vibration and minimise reaction forces within the drivetrain.

The coupling uses carbon-fibre composite engineering based on Geislinger’s experience with lightweight composite technology. The company said each unit is individually engineered to meet specific drivetrain requirements and provides low dynamic stiffness across the operating frequency range, without material ageing.

The design also incorporates misalignment capability, which Geislinger said can reduce assembly effort and installation time. Its compliance is intended to provide greater flexibility during installation and operation, while an electrically insulated design supports integration into complex drivetrain systems.

Geislinger will display the SILENCO® Neo at its stand in Hall A3, Booth 107, during SMM 2026 on 1 – 4 September in Hamburg.
