UltraLight™ Aluminum Dead Shaft Idler Rolls

Low break-away torques ideal for low-wrap, low-tension applications
Double bearings at each end keep stub-shafts true to roll
Small diameter bearings for free running performance
Dynamically balanced for high speeds

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.
