BK6
Bellows couplingsThe BK6 bellows coupling from R+W Couplings has a high degree of operational reliability and is suitable for axial mounting. The design of this precision coupling makes (dis)assembly very easy. The tapered press fit system allows the coupling to be mounted in two parts. This connection is also electrically insulating. The screws of the clamping hubs are tightened through the inside of the coupling. This friction clamp connection makes the coupling absolutely free of slippage. 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.
