Steel

Live Shaft Steel Idlers are often ideal whenever the web or the environment challenges roll integrity or performance.

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 Live Shaft Steel 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.

Any idler intended for use in elevated temperatures must have proper venting to avoid explosion. Be sure you identify such applications upon ordering.

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.
