DISCFLEX DNZ-G – Rigid coupling for industrial applications
DISCFLEX couplings are suitable for a range of industrial applications where torque is transmitted from the input shaft to the output shaft alternately through traction and compression of the flexible element.

DISCFLEX benefits
This VULKAN product offers the following benefits:

  • High speed and torque transmission
  • Small sizes
  • Low weight
  • Maintenance free
  • High torsional stiffness
  • Low axial and radial reaction forces

Alternative to flexible couplingThis is a suitable alternative to flexible couplings whenever the environmental conditions are detrimental to the elastomer. DISCFLEX couplings are suitable for operating temperatures of between -50 and 150 °C and comply with API 610 requirements.
