Lightweight Aluminum Dead Shaft Idler Rolls

When you need an idler lighter than the standard aluminum models, but stronger than an UltraLight™, take a closer look at Webex LightWeight Aluminum Idlers.

Webex LightWeight Aluminum Idlers offer you the same precision construction and design detail as our standard aluminum idlers — but with half the wall thickness and half the roll weight. Break-away torque is less and roll inertia is lowered. All this gives you a high-performance roll ideal for low tension applications.

In all other ways, Webex LightWeights are directly comparable to our standard aluminum idlers. Both are dead shaft designs using the same steel shafts and low-friction bearings. Both are precision balanced for maximum performance over a wide range of speeds. And both are available as Webex standards — offering you consistent, repeat performance roll to roll and order to order.
