Krishna Engineering Works India, offers comprehensive range of Expandable Shaft, Air Shaft for different industries. we have been manufacturing Expandable Shaft from last 25 years with premium quality to meet international standard.

Expandable Shaft

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 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.
