Type DEZ flexible rubber elements

The DEZ, DEZ-S and DEZ-R are highly durable rubber elements offering remarkable flexibility in all directions for torsional coupling applications. Their high damping characteristics and low dynamic torsional stiffness result in a low frequency drive system, ensuring that critical speeds remain below operational speeds.


  • Rubber: One piece, non-lubricated elastomeric rubber element
  • No need for lubrication
  • Sizes: DEZ65 to DEZ241, DEZ71S to DEZ285S, DEZR0422 to DEZR2022
  • Torque range:  Nominal torque up to 63,000 kNm
  • Rupture torque:  6 to 9 times the nominal torque
  • Industry applications: Marine propulsion, mining, cement, pulp and paper
  • Interchangeability: Replacement elements for Vulkan ® manufactured EZ, EZS and EZR couplings
