DX type expanding shafts may be manufactured of aluminium with an extruded profile or may optionally be made of steel or ERGAL (a special aluminium alloy which allows an approximate increase of 30% in the shaft's capacity without increasing its weight).

Depending on applications and requirements, expanding shafts may be made with expanding strips or keys to allow a proper fixing of the core reel.

For all applications where reels have to be unwound or rewound in a perfectly concentric fashion to avoid stressing the material, we have designed and manufactured a special self-centring shaft called CENTRIMAX (CX), usually used for foil materials with a thickness of only few microns.

Thanks to a pneumatic-mechanical control, it guarantees high precision reel centring.
