Key Type Friction Ring

Key Type Friction Rings For Differential Air Shaft

The use of differential shaft improves the speed of the slitter, the accuracy of the winding and the degree of automation.At the same time,it shorter the preparation time and achieve the humanized operation. In particular for polyester thin materials which have poor tensile resistance and big difference in thickness.The use of differential shaft ring can reduce the difficulty of winding.

Besides, using slip shaft to wind or unwind precious materials, metal foil and special paper roll, can greatly improve the production yield, reducing the cost of production.

Key type friction rings with double row of expanding key/lug, totally interchangeable these rings ensure a perfect locking and friction of the slits to be rewound, they are available in the following executions:
