Vulcanized Pulley Lagging

Benefits

Douglas® Truck Tire Tuff™ Conveyor Pulley Lagging delivers increased traction and pulley life over non lagged pulleys. Increased traction between the pulley face and the belt bottom covers reduces belt slippage and helps to improve belt tracking. Vulcanized rubber lagging protects the pulley’s face from wear and extends pulley service life.

  • As much as 50% increase in coefficient of friction over non lagged pulleys
  • Improves Belt Tracking
  • Protects pulley face from wear and extends pulley service life
  • Herringbone and Diamond Grooves shed water and dirt promoting a self-cleaning effect

Construction

Douglas® Vulcanized Rubber Pulley Lagging is constructed of the highest quality materials available and to the highest quality standards in the industry. All pulleys are vulcanized in house using state of the art computer controlled autoclaves and our patented bonding process.

If you have an application that requires exact concentricity or T.I.R. we suggest ordering machined lagging with the tolerance specified. For some applications the initial cost will be quickly offset by labor savings when attempting start-up.
