Slitting machine slip differential expansion shaft supplier

 Differential air shaft takes air shaft as its main body and adopt central air pressure to control the tension of the winding material .

1.Clamping reliable, low malfunction rate, the unique design makes it easy to dismount, and can replace the friction keys conveniently with no affection to the rotation accuracy.
2.Friction key materials are patented formula, good consistency of dynamic and static friction coefficient, less affected by temperature ,high wear resistance and long service life.
3.Adopting high quality 40 chrome as the shaft ,which greatly improve the bearing capacity of the whole shaft.

Rewinding or slitting of packaging materials such as:

1.web material;

2.plastic sheet material;

3.aluminum foil material;

4.PVC material;

5.plastic film material;

6.insulating material

1.The differential air shaft consists of a plurality of slip rings, which can overcome the problem of unwinding and material damage. 

2.The use of differential air shaft improves the speed of the slitter, the accuracy of the winding and the degree of automation.
