Geislinger SILENCO®

The Silenco® coupling is an acoustically optimized misalignment coupling. It consists of flanges, maintenance-free composite membranes with increased damping properties, composite shafts, and steel spacers. The coupling provides resistance to heat, frost, oil and offers electrical insulation as an option. Depending on the acoustical needs and the required torque, different versions of flanges, membranes and shafts are available.

The lightweight Geislinger Silenco® coupling is designed to minimize the transfer of the structure borne sound. Its modular system is comprised of components with the best acoustical performance. Additionally, to further optimize the coupling, special flanges made out of a combination of composite material, rubber, and steel have been specifically developed for the Silenco®. Designed to avoid resonance effects of its components, the Geislinger Silenco® coupling ensures an extensive reduction in the transfer of structure-borne noise.

All components of the Geislinger Silenco® coupling are acoustically optimized, including its

  • flanges, with or without rubber layers.
  • maintenance-free composite membranes with increased damping capabilities.
  • composite shafts.
  • steel spacers for length which can be adjusted to each type of installation.

The Geislinger Silenco® coupling is made from advanced materials and is calculated for the lifetime. They show superior chemical resistance and are electrically insulating. All components can be measured on our acoustic test beds in order proof the superior acoustical behavior.
