MK5

Miniature bellows couplings

The MK5 type miniature bellows coupling from R+W Couplings features a robust design consisting of 2 clamping hubs. One of the hubs features a tapered press-fit connection, allowing the coupling to be assembled in two separate parts. Thanks to the use of frictional clamp connections, this precision coupling is entirely free from play. Thanks to the forcibly formed bellows and the tapered press-fit connection, 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.
