EZ2
Line shaft couplingsDescription
The EZ2 intermediate shaft from R+W Couplings can bridge long distances up to 4 meters with its long design and is easy to assemble and disassemble. The concentrically machined clamping hubs provide the coupling with very smooth concentricity. Due to the press fit design, this precision shaft coupling is free of play. The EZ2 shaft coupling can be combined with 2 different types of R+W elastomer spiders, namely A and B. Both types of R+W elastomer spiders dampen vibrations to varying degrees and are electrically insulating. For specific inquiries about intermediate shafts or other precision couplings, please contact VARIODRIVE.
