XC differential shaft, also known as friction shaft. It is applied to the winding shaft of the slitting machine, and also used for the unwinding shaft in special occasions. The purpose is to use the principle of the slippage of each slip ring on the differential shaft, so that multiple rolls on the shaft can always maintain constant tension for winding and unwinding.

1. Central air pressure differential shaft, pneumatic locking, pneumatic slip. High precision, high performance, accurate torque, and precise control of tension in a wide range.

 2. Applicable to automatic roll loading shaft slip material, to ensure timing when the reversal of the core does not shift, not loose.

3. It is most suitable for the use of short shafts, and shows its excellent performance when winding metal foil, copper foil, and aluminum foil. Nishimura's special form: It can also achieve extremely low friction tension, and is applied to the slitting of the thinnest pet film and electronic film.

As people's living standards, the development of technology, higher and higher requirements for flexible packaging products, film elongation requirements of smaller and smaller, and rolling end face of increasing uniformity, which of film material Tension control puts forward higher requirements. The tension control accuracy of the winding shaft of the XC differential shaft manufacturer directly determines the elongation of the slitting product and the neatness of the end surface, so it is necessary to use the XC differential shaft.
