UltraLight™ Aluminum Dead Shaft Idler Rolls

Much lighter than Standard Aluminum Idlers … even lighter than our LightWeight Aluminum Idlers … Webex UltraLights are the ultimate in low-weight, high-performance aluminum idlers. Thanks to precision engineering and machining, the Webex UltraLight offers break-away torques as low as 0.2 oz.-in. This low-inertia idler is ideal for low-wrap, low tension applications — in particular, wherever web slippage is unacceptable. UltraLights weigh as much as 60% less than Standard Aluminum Idlers — 25% less than Webex LightWeights. Each UltraLight™ is made entirely of aluminum except for bearings and shafts.
