Differential shaft is a relatively advanced shaft for rewinding, which is suitable for users with higher requirements. A multi-roll material can be rewind at the same time on one shaft. When a roll material is too tight, the slip ring will slip with the shaft to achieve a perfect rewinding. It effectively improve the slitting speed, winding accuracy and degree of automation.



Air differential shaft are made of core roll, differential ring, rubber tube, friction parts, sealing rings.

The body of the air differential shaft is made from chrome-plate steel or hard anodized aluminum. The friction plate can be made from polyurethane, polyethylene, or rubber to max tension required.

According to the drawing, we can make steel shaft head with different sizes.
