Expandable Shaft

This is a lug type shaft but core holding is initiated mechanically and not pneumatically. This Expandable Shaft mainly consists of slotted pipe, steel lugs, brass cam, ratchet etc.

We are Air Shaft, Expandable Shaft, Pneumatic Shaft, Air Chuck manufacturers are capable of taking any challenge arising out of heavy load and speed. It is possible only because of positive gripping and core centering achieved without any extra efforts with the help of cam/lug design. It is very much advantageous with cores having uneven inside diameter. Key and alien-cap bolt prevent any shearing of journals – pipe assembly. Air Shaft manufacturing for Slitting Machine.

Economic model for Re-winder shaft having all the advantages like slippage, accommodating gauge variation, smaller core width etc. With only limitation of time needed for repositioning of the core. This shaft is suitable for Paper Cores.

 Sizes:

In case of failure of bladder, though having least chance, shaft can hold the core till the process complete.

Damaged bladder can be changed easily, even on the machine.

Expanded area is available almost all over the length of pipe body. Very small width of the cores is possible to hold.

This is a very commonly used shaft. It mainly consists of slotted pipe, journals to suite users machine, lugs, rubber bladder and non-return valve.

Sizes:

This type of shaft mainly consists of slotted base pipe, metal leaves with knurling/serration, rubber bladder, non-return valve and suitable journals.

This type of shaft can be used at unwind station, but mainly used at rewind stage for advantages like:
