Shaft Idler Rollers Eliminate Trapped Air

The innovative WINertia AV aluminum dead shaft idler rollers eliminate trapped air, along with scratching, slipping, bunching and side movement in a more effective, less costly roll solution than traditional spiral groove. WINertia AV rollers remove air 7.5 times faster and have 15 times the air parking capacity. WINertia AV idlers outperform spiral grooving, cork, and rubberized tapes for maintaining traction. They have been tested on encoders, re-winders, high-speed printers, and converting equipment running 500 to 3400 FPM. Test results have proven that the WINertia AV idlers operate at web speed, while rolls equipped with other technologies don’t keep up.
