Our mechanically clamping, patented differential elements can be produced with a minimal width of 4mm. The elements consist of only two parts, a body consisting of high-quality plastic material and a clamping yoke.
If the winding core is twisted against the winding direction, the clamping yoke catches in the core, expands and clamps.
The elements can be driven both by rubbing ledges at the interior diameter or by fin sheets and axial pressure.
