Operating principle
The Semiflex coupling is a torsionally stiff  and restoring-force-free precision coupling. In addition to the compensation of axial and angular displacements, it provides high radial displacement capacity together with compact design.
The displacement compensation is restoring force-free and takes place via the unique system of two pairs of elements offset by 90°. The angle synchronisation of the connected shafts is retained at all times.

Dynamic D Line – The lightweight aluminium line
The lightweight aluminium line with low mass inertia – the Dynamic line is designed for applications with high angular accelerations.
The Dynamic line is available for nominal torques up to 180 Nm. For backlash-free shaft connection, the couplings of this line are basically equipped with clamp hubs.
