Technical Specifications

For advanced converting applications, this Air Expanding Shaft can be integrated with a Tension Control System to achieve precise Web Tension Control throughout the production process.

In high-speed slitting lines, a Differential Shaft helps maintain consistent tension across multiple rolls and improves finished roll quality.

To ensure stable torque control, many manufacturers combine air shafts with a Magnetic Particle Brake during unwinding and a Magnetic Powder Clutch during rewinding operations. Magnetic particle brakes provide precise and stable torque output, making them ideal for tension control applications.

XW Machinery also offers complete Slitting Machine Solutions for printing, packaging, film, paper, foil, textile, and lithium battery industries.

For improved winding stability, the adjustable diameter air expanding shaft can be combined with a web tension control system to reduce roll defects in high-speed slitting machines.

XW Machinery also supplies differential shafts and slitter rewinder machine parts for advanced converting production lines.

In modern industrial systems, magnetic powder clutch technology is often used together with pneumatic shafts for precise torque regulation.
