The requirements are clearly defined: absolute torsional rigidity, good damping properties, and precise, virtually forceless compensation of shaft misalignment. This is precisely where metal bellows couplings demonstrate their strengths. The thin-walled bellows reliably compensate for misalignment errors while simultaneously dampening vibrations – a major advantage in continuous operation at high speeds.

One example is the KSS metal bellows couplings from Jakob Antriebstechnik. Their twin-wave bellows with a straight intermediate piece offers high flexibility. Thanks to tapered bushings as the shaft-hub connection, assembly is quick and secure, even with small shaft diameters and without the need for an additional key.

The rotationally symmetrical design ensures excellent dynamic performance, even at very high speeds. With their high torsional rigidity, minimal restoring forces, and low moment of inertia, KSS couplings meet the most stringent requirements. They are available in torque ranges from 25 to 2500 Nm.

The combination of the highest manufacturing quality and durable materials makes these couplings a reliable and cost-effective solution – not only in high-speed test benches, but also in servo and actuator drives.
