en acier à haute résistancede bobinage à frictionexpansible

Product Overview
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 solves uneven tension issues in multi-roll slitting and rewinding by providing independent tension control for each rewind core, ensuring consistent winding quality and reducing material waste.

Principle of Operation
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 rewinding. 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.
