EZV

Line shaft couplings

description

The EZV intermediate shafts from R+W Couplings can cover long distances up to 4 meters with its long design as a standard feature. The unique design allows the user to adjust the length as desired during installation. The shaft coupling is easily (dis)assembled due to the split clamping hub construction. The concentrically machined clamping hubs provide the shaft coupling with very smooth concentricity. The press-fit design makes this precision coupling free from play or backlash. The EZV shaft coupling can be combined with two different types of R+W elastomer stars, namely A and B. Both types of R+W elastomer stars dampen vibrations and are electrically insulating. For specific inquiries about intermediate shafts or other precision couplings, please contact VARIODRIVE.
