MKH

Miniature bellows couplings

The MKH type miniature bellows coupling from R+W Couplings features two fully split clamping hubs, making it easy to assemble. Additionally, this precision coupling is highly suitable for integration into compact spaces. The MKH coupling has a low moment of inertia, and due to the use of frictional clamp connections, the coupling is entirely 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.
