Gas fill type/ mechanical type for winding machine friction shaft,differential rewind shaft
Reliable Quality,Reasonable Price and Good Service.
Brief introduction
Differential Shafts are designed to be easy to use and relatively maintenance free, ensuring the highest winding quality, even when rewinding very narrow rolls – down to 9mm in width. The Cores are gripped by friction rings which run on a central shaft that is treated in order to provide a hard surface, with a relatively low coefficient of friction, over which the friction rings can rotate. The tension ranges of the shafts are varied by changing the expanding strip material of the centre shaft which provides the slippage. By designing the rings to slip internally, common issues have been eliminated in comparison to other differential shafts.
Performance and advantages
• NO core dust in the mechanisim.
• Cores can be reused
• Sideway slippage eliminated
• Positive expansion and retraction to a consistent diameter
• Duplex and multiple tension applications
Product usage
It is widely used in printing, cutting, coating, compounding and other machineries’ releasing and winding scroll.
Note:
This type have two kinds 45# steel and aluminium alloy, we recommend aluminum alloy tube if normal load weight less than 800kg and length less than 1500mm.
All the specification can be customized.

FAQ
Order Guide:
User should specify type,dimension,the position of gas nozzle,and the tolerance of the important size of the top of the shaft.All formal drawing of overall dimension should be provided.After the confirmation of both sides,we will start production.
1. Can I know which type of friction shaft do you need? Mechanical type or gas fill type(Same price).
2. The number of friction element matters a lot to the price, so can you confirm it's element quantity?
3. All the shaft specification can be customized. Could you please sent us your require drawing?
