Air Roll Lock Differential Shaft
Differential Winding Air Core Shaft
Availability: 2-4 Weeks - Made in the USA- Slip is internal which means: no core dust, no side to side movement, no core wobble
- GlideLock(TM) Clutched Rollers feature an internal slip mechanism
- CoreLock(TM) bearings grip cores firmly on loading, ensuring only the correct rollers lock on actuation
Product Overview
Air Roll Lock Differential shafts are best suited for both wide and narrow web applications. Perfect for multiple width rolls and materials on the same air shaft, these shafts ensure consistent tension across all rolls.
With recent advances in our Air Roll Lock Differential shaft design, we’ve taken the pain out of differential winding. Using an internal clutching mechanism to control tension eliminates operator error and can dramatically improve roll quality. The integrated GlideLock rollers allow easy loading and unloading of heavy rolls.
What are our customers saying?
“Since we installed the Convertech Differential Shafts on our Dusenbery 835…, we have had nothing but an increase in production due to less downtime. Not only can we run many different film widths across the shafts, but we can still maintain proper tensions…”

More about the Convertech Air Roll Lock Differential Shaft
Convertech Air-roll-lock differential air shafts slip internally to use multiple width rolls and materials on one air shaft. Always custom-made, these shafts lock for a precision fit and are available in several mounting styles.
Because Convertech Air Roll Lock Differential Shafts slip internally, we have eliminated the common issues still found in our competitors differential shafts.
USAGE: Slitting/Rewinding where multiple roll widths are running on one air shaft.
