Commonly used on shaftless unwinders, it’s possible to switch to larger diameter cores by rapidly mounting adapters on the body chuck.

Pneumechanical and perfectly self-centering they transmit very high torques.

Adapters for large core diameters up to 300mm are rapidly mounted on the standard body chuck for 70 mm and 3” inside diameter cores.

The Safe-Grip chucks provide perfectly concentric expansion, great load capacity and transmit very high torques.
