When a steel live shaft idler isn’t light enough, consider aluminum. Webex has simplified the ordering process by offering standard models with pre-engineered specifications. You determine the journal configuration, roll diameter and face length needed to meet your application.

Live shaft idlers have several application advantages:

High Loads
Self-aligning pillow blocks and flange bearings used to mount live shaft idlers are capable of handling higher loads than comparable dead shaft idlers using rigid bearings.

Elevated Temperature*
Webex Aluminum Live Shaft Idlers can handle substantially elevated temperatures with proper venting. This makes Live Shafts ideal in ovens where an elevated temperature or solvent atmosphere would quickly destroy dead shaft roll bearings.

Harsh Environments
By positioning the roller bearings out of the immediate web path, exposure to process contaminates is minimized. That’s why Live Shaft rolls are often ideal in applications where chemicals, dust or vapors commonly destroy dead shaft roll bearings.
