MK1

Miniature bellows couplings

The MK1 type miniature bellows coupling from R+W Couplings features an economical design consisting of 2 hubs with radial set screws and an integrated disassembly groove. As a result, a special design for disassembly on the shaft is not necessary. This precision coupling is torsionally rigid and 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 these do not fall outside the maximum range, there will be no metal fatigue in the bellows material, and the coupling will be completely free from wear. For specific inquiries about miniature bellows couplings, please contact VARIODRIVE.
