Torsionally rigid, flexible coupling
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.

FLEXDUR
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

FLEXDUR
General technical description

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.
