The air chucks are an ideal solution for winding and unwinding rolls with different core diameters with only one shaft mounted. The air chuck is easily and firmly fixed on shaft via compression flange. After inflation through valve chuck extends its diameter and perfectly fixes the core by its rubber body. The huge advantege of adaptors is no need to buy expensive unwinding shafts for every used core diameter, they are also easy to manipulate and operate.It is available with side flange for mobile arms unwind stand mounting which makes it easy for operator to install the chuck into the exact position or with a passing bore for passing bars mounting with one inflation valve for both
For higher bearing capacity or torque it is possible to connect more air chucks in one series.
