PORA
PRB-YF4.5 Type
The PRB-YF4.5 Type is a forced-air cooled powder brake engineered for precise and reliable tension control in industrial winding applications, such as paper, film, yarn, and wire. Its forced-air cooling system ensures efficient heat dissipation during high-speed or high-load operations, enabling consistent torque delivery and prolonged performance. Designed for easy integration with various tension controllersmanual, semi-automatic, or automaticit offers enhanced production stability, operational efficiency, and longevity in demanding environments.
