FlexDur FD-HS

FlexDur FD-HS

FLEXDUR FD-HS all steel couplings are designed and manufactured to meet highest standards, particularly in high rotational speed applications. The coupling uses bushed flexible disc packs of stainless spring steel as power transmitting elements. The special shape of the precision bushes ensures a uniform stress distribution across the mounted disc pack and high grade fitting bolts enable a backlash-free torque transmission.

The most important characteristics and advantages of FlexDur FD-HS couplings:

  • Torsionally rigid and backlash-free torque transmission
  • Directly adaptable to HBM torque transducers
  • Suited for very high rotational speeds
  • Compensates for axial, radial and angular misalignments
  • Low reaction forces in case of shaft misalignment
  • Low mass moments of inertia through high power density
  • For use at ambient temperatures from 35 °C up to +110 °C
  • No maintenance or lubrication required
  • Almost unlimited lifetime and wear-free with proper shaft alignment

Product details


The disc pack is laid out such that it combines high torque capacity with high rotational speed capability; it is specifically designed for test bench applications. The series covers a nominal torque range from 320 Nm up to 12500 Nm. The permissible rotational speeds are adjusted to the requirements of the test specimens.


The FLEXDUR FD-HS coupling is made up of modular components and as such adaptable to the most varied mounting situations:
Designed as a torsionally rigid double-joint coupling with two flexible disc packs, it compensates for axial, radial and angular misalignments and is thus flexible in all directions. Multiple installation lengths are available as standard. The FLEXDUR FD-HS is supplied as standard with clamping hubs for shrink disc connection and provides a completely backlash-free connection between the shaft and the hub.
