Product overview :
Webex Dead Shaft Aluminum Idlers are some of the most versatile and hardworking idlers on the market today. Weighing nearly half as much as comparable steel rollers, aluminum idlers still provide exceptional performance across a broad range of applications. This reduced weight makes them ideal for applications requiring lower web tensions and minimal web wrap.
Standard Aluminum Idlers are dynamically balanced at speeds up to 2,000 FPM. Each one is precision machined to exacting tolerances. Only the smallest aluminum idlers (2" and 2-1/2" diameter models) have a 1/4 inch thick roll wall. All other standard aluminum idlers are made from 1/2 inch wall material.
