R+W offers two different types of backlash-free shaft lines: with metal bellows or with elastomer insert.

The vibration-absorbing shaft lines with an elastomer insert as an intermediate piece absorb and compensate for vibrations and sudden torque variations. They can typically cover distances of up to four meters, are available with inner diameters between 5 and 140 millimeters and transmit peak torques of up to 25,000 Nm.

Torsionally rigid shaftlines are very similar to metal bellows couplings - both in terms of structure and technical properties as well as in their high torsional rigidity and low restoring forces. Thanks to their internal support with a special Cardan joint, the intermediate axes with metal bellows make it possible to cover distances of up to six meters and to compensate for axial and angular misalignments. Additionally, the critical rotational speed in bending is increased by the support, resulting in increased operating speed. The torsionally rigid intermediate axles cover a torque range of 10 to 1000 Nm and an internal diameter of 5 to 100 mm.
