Nickel bellows couplings with clamping hubs

The BKNK 1733 and BKNK 2537 nickel bellows couplings are miniature couplings for high-precision measuring tasks with stress-free nickel bellows and mounting featuring clamp hub. The installation dimensions can be deduced from the article designations: the first two numbers indicate the diameters of 17 and 25 mm, the following numbers the overall lengths of 33 and 37 mm. Like the versions with screw hubs, they have a very very high torsional rigidity with low restoring forces and optimum compensation of misalignments thanks to their highly flexible bellows.
