Mechanical Expanding Shafts

Shafts designed after the mechanical stretching principle guarantee 100% centrical roll mounting. The operational area is for high web speeds and / or low circular run-out tolerance. Thus, sensitive materials like metal foils can also be wrapped precisely.

The activation of the shaft is done over a hexagon in the axle journal. This construction makes it possible to use all kinds of screw systems, primarily pneumatic screw spanners.
