Chucks with strips
They differ from the expanding airshafts because they have got no journals; they are provided with a through central hole to be mounted on steel bars or on expanding airshafts.
They body is made from natural or surface anodized aluminium.
The expanding strips are from aluminium or rubber-steel.
The strips can expand thanks to multiple bladders from synthetic high-strength bladder.
The clamping to the underlying airshaft is ensured by a clamp assembled to the chuck.
They are available from min. diam. 48 mm up to max. 200 mm .
