POLY-NORM M torsionally flexible, fail-safe shaft coupling


0 - 5,500 kNm / torsionally flexible, fail-safe shaft coupling

The torsionally flexible, fail-safe shaft coupling POLY-NORM-M is a three-part large coupling mainly used in applications with high torques and drives subjected to shocks.

It is specifically solid, fail-safe, compensates for any kind of shaft displacement while transmitting high torques reliably.

Several elastomer series arranged one after another allow to transmit high torques with comparatively compact outside dimensions and take large shaft diameters up to Ø 900 mm.The three-part design of POLY-NORM-M allows to replace elastomers when installed.


  • torques up to 5,500 kNm

  • shaft diameter up to Ø 900 mm

  • compact outside dimensions, since elastomers are arranged one after another

  • compact: small shaft distance dimension

  • damping vibrations
