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.
