Webex Carbon Composite Idlers are unmatched for their combined qualities of strength and low weight - only a third of the weight of a comparable standard aluminum idler with 1.2 times the load bearing capacity. These high performance idlers use carbon fiber composite tubing for the roll shell. A special steel stub-shaft and lightweight aluminum headers keep total roll weight to a minimum.

These remarkable idlers are ideal for running wider, lighter weight webs at higher critical speeds. Inertia ratings are the lowest of any roller on the market. Best of all, you can specify them now as a Webex standard - saving you the expense of a custom carbon composite idler.
