These flexible couplings are loaded with polyurethane teeth elements. They reduce intermittent short period torsional shocks by briefly storing the shock energy. Any degree of uneven movement and load transfer is consequently reduced. Elastic couplings restrain body resonance, and therefore contribute to noise reduction. The elastic element transmits the torque safely preventing break-down. These couplings perfectly replace Rotex/Spidex brands.

Engineers may also be interested in high performance couplings similar to Spidex. More information can be found below:
