Air‑Driven Mechanical Chuck
The air‑driven mechanical chuck is forged from a single piece, delivering excellent rigidity and strength.
It is the ideal choice when the core must be locked without any torque for transmitting high torque values and/or operating at high working speeds. Driven by air pressure, the expansion device expands and securely locks the core in position.

Rotary Mechanical Chuck
Rotary mechanical chucks are widely used in winders and unwinders for slitting, cross‑cutting, rotary knife, paper‑making and corrugated paper industries.
They deploy jaw components by the movement of the reel shaft to automatically lock and centre the core. Thanks to its simple yet innovative working principle, the chuck maintains high‑performance even in dusty environments, as the jaws are deployed merely by rotating around the central cam.

Side‑Push Mechanical Chuck
Built with robust components, simple movements and optimal gripping force, the side‑push mechanical chuck features long‑lasting durability under all production conditions, and performs excellently during winding and unwinding of rolls of any size and material. It prevents core damage and delivers reliable gripping force for all core materials.
Fitted with a spring system, the side‑push mechanical chuck deploys a set of keys via axial thrust once inserted inside the reel core, so as to ensure proper clamping of the reel shaft.
