Torsionally stiff bellows couplings

Zero backlash, torsionally stiff and highly accurate - Precision couplings from R+W

High precision, zero backlash and torsionally stiff: Bellows couplings from R+W

The AKN metal bellows coupling is extremely compact with a short design. Due to the shorter bellows, it is very rigid but is still able to compensate for misalignments.

The AKN-H metal bellows coupling is identical to the standard AKN type, except that it has half shells to enable installation and removal without having to move the attached parts axially.
