Flexdur

Torsionally rigid, flexible coupling. Using bushed flexible disc packs of stainless spring steel as power transmitting elements. The special shape of the precision bushes results in a uniform tension distribution of the disc pack.

The coupling uses bushed flexible disc packs of stainless spring steel as power transmitting elements. The special shape of the precision bushes results in a uniform tension distribution of the disc pack. The high grade fitting screws ensure backlash-free torque transmission. The FLEXDUR (short form: FD-C) has a modular design and can therefore be adapted to a wide variety of installation situations:

FLEXDUR 2 (e.g. type S) as a double-jointed coupling with two flexible disc packs compensates for axial, radial and angular displacement and is therefore flexible in all directions. Different mounting lengths are available as standard.

Advantages

  • Torsionally rigid and backlash-free torque transmission
  • Compensation of axial, radial and angular shaft displacements
  • Small restoring forces at shaft displacement
  • Neither maintenance, nor lubrication required
  • For use at ambient temperatures from –25 °C to +250 °C
  • Compact design, also suitable for high speeds
  • Almost unlimited lifetime and wear-free at proper shaft alignment
  • ATEX
