Metal bellows couplings from the 'AK' series have been designed especially for the backlash-free transmission of high torques of up to 5,000 Nm. The elements are mounted on driver and driven components with tapered clamping bushings. Depending on the required size, the coupling will be produced with hubs made of aluminum or stainless steel. In addition, AK guarantees for perfect concentric running.
