MK4
Miniature bellows couplingsThe 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 required. This precision coupling is torsionally rigid and completely free from play. Thanks to the forcibly formed bellows shape, the element can simultaneously accommodate lateral, axial, and angular misalignments. As long as they do not exceed the maximum limits, 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.
