BK5
Bellows couplingsThe BK5 bellows coupling from R+W Couplings is designed to be easy to (dis)assemble. The tapered press fit system allows the coupling to be mounted in two parts. This connection is also electrically insulating. By using friction clamp connection, this precision coupling is absolutely free of backlash. Thanks to the forced-shaped bellows, the element can simultaneously accommodate lateral, axial and angular misalignments. As long as they do not fall outside the maximum area, no metal fatigue will occur in the bellows material and the clutch is completely free of wear. For specific questions about bellows couplings, contact VARIODRIVE.
