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:

Highly Corrosive Environments
High moisture environments can rust and corrode steel idlers. Webs made of PVC materials can form hydrochloric acid. Certain processes require the use of caustic solutions. All these can damage steel and impact the performance of standard steel idlers. For more aggressive environments, other stainless steel grades are available.

Elevated Temperature
Webex Live Shaft Stainless 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.

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. For greater wear-resistance, Stainless Steel Idlers can be readily plated with plasma coating, nickel or chrome.
