Pneumatic slitter scorer expanding shafts mod. 642 PM
Pneumatic slitter scorer expanding shaft model 642 PM is recommended as a drive shaft for slitter, scorer, or slitter chucks and represents an alternative to the traditional non-expanding drive shafts.
The body of the shaft is available in chromed grinded steel only, and expanding ledges are in rubber. The journal ends are also available in a variety of steels and are always custom-made. 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, granting this way a perfect core gripping. Tube changes are quick and easy, accomplished without journal removal. Hex sockets free both expandors and tube for a quick procedure.
