Please Provide Technical Information for Offer Of Air Shaft (Please Click)

Differential Shaft is a sophisticated winding shaft for slitter re-winder machine, used as duplex shaft winder (centre winding type).

• It is capable of compensating speed variation due to gauge variation with multi cores.


• Minimum 20 mm core width is possible.


• Reel holding is possible at any position across the width.


• No-time lost in re-positioning cores since no distance pieces are required.


• Shaft can run at very high speed.

This shaft consists of slotted shaft, rubber bladders, hard and ground steel cage with ball type gripper. Teflon® strip for better slippage and self lubricating segments separating two adjacent steel cages.

• Suitable for core ID. 3" and 6"


• Length as per requirement.

• Load up to 2 tons


• Suitable for Core l.D. dia 3”, 4”, 6”, 8” (metric size and special sizes also produced)


• Length as required


• Speed up to 1000 mtrs/min


• Suitable for core materials: Paper, Steel, Thermoplastics


• Minimum core width 20 mm

• Pipe - Steel


• End Generals - Steel - simple or hardened


• Cam - Brass


• Lugs - Hardened Steel / Rubber

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

The shaft is 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.

• Suitable for Core ID. 3" and 6"


• Length as per requirement

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.

• Suitable for core I.D. 3", 4" & 6"


• Length as per requirement


• Individual Quick Locks are also available having width of 50 mm, 75 mm, 100 mm and 300 mm. The bore of Quick Lock is tailor made.

• 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.

These types of shafts are suitable for both unwinding and winding stages. It can accommodate single core, multi cores of the width more than 150 mm. Type of pipe material, lug material are decided based on duty conditions like load, speed and core material. The limitations are, it can not take care of gauge variation or individual core speed variation since slippage is not achieved and core width less than 1 50 mm.

• Suitable for Core ID. dia 3", 4", 6", 8" (metric size and special sizes also produced)


• Lengths as per customers requirement

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:

• Narrow width of core


• To prevent damage to thin cores (100 % support available to the core ID.)
• At times core-less winding is also possible

This also has a limitation to accommodate gauge and speed variation.

• Suitable for core ID. 3, 4 and 6 (metric size and special sizes also produced)


• Lengths as required
