'gripping force'

AIR POWER CHUCK Rotation of the chuck in either direction is possible Best option for avoiding core damage in shaft less machines → No axial force is applied: hence better life of winding and unwinding station. → Concentric expansion and gripping force → Quick-Change between core sizes with slide-on core chuck adapters. → Unmatched torque capacity at higher speed & jam free operation → Can be used for any core material without alteration

Mechano-Pneumatical Core Chuck (Spring-Force Expanding) Axial-thrust mechanical chucks with double diameter cores 3" and 6". The chuck expansion occurs by axial thrust of t h e c h u c k i n s i d e t h e c o r e The lugs are k e p t a t t h e minimum diameter with t h e help of spring force. FORTUNE axial thrust mechanical core chucks are provided with a spring system which, using the axial thrust when introduced inside t h e reel core, e x p a n d a series of keys That guarantee t h e right grip of t h e reel.
