Highly Flexible CouplingVULASTIK L

[Translate to English:]

The VULKAN VULASTIK L highly flexible coupling is an axial pluggable highly flexible coupling developed for a variety of different applications. Four rubber qualities and silicone coupling are available in order to tune the coupling to the various system requirements. VULKAN VULASTIK L highly flexible couplings are available with one elastic element in standard design or as dual execution with two parallel elements. The main parts of the VULASTIK L highly flexible coupling are the hub and a flanged casing. Between these, the disc-shaped element is arranged. This disc element is vulcanized at its inner radius, the outer radius is connected to the flanged casing by a plug-in toothing. This toothing provides the axial plug-in feature and compensation of shaft displacements.


  • Vulkan highly flexible couplings with maximum flexibility is provided by different torsional coupling designs for installation in bell-type housings or free-standing installations, designed with single or dual arrangement of natural rubber or silicone
  • There is an extremely compact design for more efficient engines with high power density. This spline enables axial engagement with ease of assembly
  • Integrated supporting rings protect against slipping through or developing cracks in the gearing teeth
