ZA (10–800 Nm)

Line shaft couplings


The ZA intermediate shaft from R+W Couplings can bridge long distances up to 6 meters with its long design and is easy to assemble and disassemble. Additionally, the ZA intermediate shaft is torsionally rigid, and due to the use of friction clamp connection, the precision shaft coupling is completely free of play. Thanks to the forcibly formed bellows shape, the element can simultaneously compensate for lateral, axial, and angular misalignment errors. As long as they do not exceed the maximum range, there will be no metal fatigue in the bellow material, and the shaft coupling will be entirely free from wear. For specific inquiries about intermediate shafts or other precision couplings, please contact VARIODRIVE.
