The following standard models are provided for ease of ordering. Custom configurations are available.

Use the Specifying Graph (included below each standard model) to determine if your specifications fall within safe or acceptable parameters. The light blue bands identify the maximum safe operating speeds for given load and face widths. If your criteria places you in the yellow band, call the Webex customer support team to assist you in sizing your roll. If your specifications place you near band borders — or do not fit the parameters suggested in these graphs — call us at (920) 720-6666 for help. Have information ready on speed, web tension and wrap angles.

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.
