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
