Spiral and Spiral Plus Wing Pulley

Continuous belt contact that eliminates excessive noise and vibration.

The PPI Spiral Wing and Spiral Plus Wing pulleys are formed by winding flat bar spirally from the center of a wing pulley to the outside ends. This continuous belt contact design eliminates noise and vibration, while still providing a cleaning effect and allowing a path for debris to escape rather than being trapped between the pulley and belt.
