High expansion mechano-pneumatic chuck

A robust chuck for big diameters

Designed for machines called "between points" with mobile frame, these chucks always work in pairs even if only one motorized or braked. The large expansion allows flexibility in the diameter of the cores. These chucks are suitable for high torque and heavy load applications. Changing core diameter is very fast. Pneumatic operation "mono-stable" allows easy installation in an automated machine. Steel jaws are suitable for the use of cardboard, plastic or steel mandrels. MPGE type head range allows the use of 70 to 400mm diameter cores.
