Présentation
Also known as Ball Type Differential Air Shaft, Pneumatic Differential Shaft, or Slip Differential Shaft, this product is designed for precision slitting and rewinding applications. It provides independent tension control for each rewind core, ensuring consistent winding quality and reducing material waste.

Fonctionnalités principales
Using advanced pneumatic friction ring technology, each friction ring can slip independently to automatically compensate for web thickness variations during rewinding. The system maintains uniform web tension across all rolls, preventing wrinkles, telescoping, loose winding, and roll deformation. Compared with conventional air shafts, ball type differential shafts offer more precise tension control and are especially suited for narrow web slitting and lightweight materials.

How Ball Type Differential Shafts Work
A Ball Type Differential Shaft uses independently controlled friction rings mounted on the shaft body. Pneumatic pressure activates steel balls inside each friction ring, generating controlled slip torque during the rewinding process. When differences in material thickness, winding tension, or roll diameter occur, each friction ring automatically compensates by slipping independently, ensuring equal web tension across every rewind core and improving rewinding quality.
