BKS
Bellows couplingsThe type BKS bellows coupling from R+W Couplings is made entirely of stainless steel and can withstand high temperatures. The clamping hubs make the coupling easy to assemble. Its short length makes this coupler very suitable for installation in compact spaces. Thanks to its forced bellows shape, the element can simultaneously accommodate lateral, axial and angular misalignments. As long as these do not fall outside the maximum area, there will be no metal fatigue in the bellows material and this precision clutch is completely free of wear. For specific questions about bellows couplings, contact VARIODRIVE.
