PUFlex EC Coupling

PUFLEX EC couplings are the three piece assembly of 2 no. Steel hubs and one Special Grade Polyurethane element. These three pieces are assembled to complete the PUFLEX EC coupling. After assembly these couplings becomes sufficient flexible, backlash-free, positive motion transmitting fail safe coupling elements. Due to Polyurethane element, both the metallic hubs are separated from each other to avoid there physical contact. This helps to avoid the electrical and frequency isolation of both the connected driver and driven elements.

Ordering Code : PUFlex EC XX-YY-ZZ

XX : Size of Coupling
YY : Inner Diameter of first side
ZZ : Inner Diameter of second side.
