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:

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.
In addition to the standard FD-C version a design with strengthened discs, FD-CL, is available. Special designs e.g. for vertical mounting positions are possible on request.
For totally backlash free connection, designs with clamping hubs can be used.
