BoWex-ELASTIC®HEW is a highly flexible plug-in shaft coupling. It dampens torsional vibrations,
reduces shocks and insulates structure-borne noise.
The BoWex-ELASTIC®HEW coupling compensates for relatively large shaft displacements, for
example caused by inaccuracies in production, thermal expansion etc.
