Hollow Shaft Magnetic Powder Brake: Applications & Installation Guide

Introduction

  A hollow shaft magnetic powder brake is a core tension control component widely used in industrial winding and unwinding systems. With a hollow shaft design, it enables direct shaft mounting for easy integration into machinery. It provides smooth, precise, and adjustable torque through magnetic powder, ensuring stable tension during material processing.

What Is a Hollow Shaft Magnetic Powder Brake?

  It is a type of electromagnetic brake that uses magnetic powder as the torque transmission medium. When energized, the magnetic field solidifies the powder, generating braking torque. The hollow shaft structure eliminates the need for complex couplings, saving installation space and simplifying mechanical layout.

Key Applications

1. Film & Foil Processing

  In film production, slitting, and rewinding, consistent tension is critical to avoid wrinkles, stretching, or breakage. The hollow shaft magnetic powder brake delivers precise tension control for thin films, PET, BOPP, and aluminum foil.

2. Textile & Paper Industry

 Used in yarn, fabric, and paper winding systems to maintain uniform tension and improve product quality.

3. Printing & Packaging

 Ideal for label printing, flexible packaging, and coating machines, ensuring stable unwinding tension for high-speed production.

4. Wire & Cable Manufacturing

 Controls tension during wire drawing and cable winding, preventing wire breakage and ensuring consistent winding density.
