740 PL – Pneumatic expanding chuck with ledges

Description

The 740/PL air chuck is recommended for unwinding and rewinding with cores, where perfect centering is needed.

The chuck body is available in steel or aluminium, and the expandors in steel, rubber, plastic or in combination, depending from the application.
It is available with side flange for unwind and rewind stands mounting, or with a passing bore for passing bars mounting.

Expansion is obtained by a system of inflatable tubes that are located beneath each row of expandors.

Each tube exerts pressure equally to engage the expandors when air is applied, obtaining this way greater self-centering qualities.

To get better performances in load capacity and transmittable torque, the number of expandors can be increased or, as an option, three or more 740/PL chucks can be connected in series.

Standard sizes available for this Model are listed on the download-sheet, but are available in other sizes for a custom order.
