Clamp-style couplings attach an encoder shaft to another rotating shaft to transfer rotation between the shafts in a precise manner. They also reduce wear and tear on bearings that can lead to costly maintenance and reduced life of your encoder. Using EPT couplings will help extend the operational life of your encoder and guarantee accuracy. The construction of a EPT Coupling consists of 2 hubs (that attach to the shafts) and a center flex member. This flexible element is affixed to the hubs through pins. Clamp-style hubs provide a positive, secure shaft connection. The clamp-style EPT Couplings are available with a single flex disc for standard torque capacity, or with 2 flex discs for increased torque capacity, torsional stiffness, and length.
