The XW Machinery Hollow Shaft Magnetic Powder Clutch is designed for precision torque transmission and constant tension regulation in winding and unwinding applications.

For complete tension management, this clutch can be paired with a [Magnetic Powder Brake] to create a highly efficient closed-loop tension control solution. The combination ensures smooth material handling and stable roll quality throughout production.

When integrated with a [Tension Control System], the clutch automatically adjusts torque according to changing roll diameters, helping manufacturers maintain consistent tension from start to finish.

Its fast response characteristics make it especially suitable for demanding [Web Tension Control] applications involving film, paper, foil, textile, nonwoven fabric, copper foil, and lithium battery materials.

In multi-roll slitting operations, the clutch is frequently used together with a [Differential Shaft] to ensure even winding tension across each finished roll and minimize wrinkles or telescoping issues.

For faster core loading and unloading, many manufacturers combine the clutch with an [Air Expanding Shaft], improving production efficiency while reducing machine downtime.

Customers looking for complete converting equipment can also explore our [Slitting Machine Solutions], which integrate advanced tension control technologies for high-speed and high-precision production lines.

FAQ

What is a hollow shaft magnetic powder clutch?

A hollow shaft magnetic powder clutch is a torque transmission device designed for precise tension and torque control in industrial winding and unwinding systems. The hollow shaft structure allows easy installation directly onto machine shafts, making it ideal for compact equipment layouts and high-efficiency web handling applications such as slitting, rewinding, printing, and film processing machines.

How does a magnetic powder clutch work?

A magnetic powder clutch works by magnetizing internal magnetic powder through an electromagnetic coil. When DC current is applied, the magnetic powder forms magnetic chains between the input and output sections, transmitting adjustable torque. The transmitted torque changes proportionally with the excitation current, enabling accurate web tension control and smooth continuous slipping operation.

What are the advantages of hollow shaft design?

Hollow shaft magnetic powder clutches offer several advantages:

• Easy direct shaft installation
• Compact machine integration
• Reduced alignment errors
• Stable torque transmission
