STEEL ROLLERS
We engineer Steel Idler Rollers for a vast field of converting guides since it developed with the strength to withstand substantial loading from nips, wrap angle, and high web tension. Steel Idlers also work well in elevated temperatures up to 212 degrees F (100 degrees C) with a lesser thermal expansion rate than aluminum.
We supply both Dead Shaft and Live Shaft Steel Idler Rollers. Both types can be customized with air-entrainment grooves, hard coat anodizing, cantilevering, bearings inserts, cork, plasma, and rubber coverings.
Dead Shaft Steel Idler Rolls
- DOM Tubing machined for minimal stock removal
- 32 Ra finish on the roller face
- Dynamically balanced to ISO grade G6,3
- Straightness over roller face width within the greater of 0.002” or 0.0005”/ft of face length
- Low-Friction bearings
Live Shaft Steel Idler Rolls
- DOM Tubing machined for minimal stock removal
- 32 Ra finish on the roller face
- Dynamically balanced to ISO grade G6,3
- Straightness over roller face width within the greater of 0.002” or 0.0005”/ft of face length
- Journal Material 1018 Carbon Steel
- Journal run out to roll O.D. within 0.003″
DEAD SHAFT vs. LIVE SHAFT
When you decide to purchase idler rollers, you will need to choose either a live shaft or a dead shaft. Each has its key advantages and the decision depends solely on your unique manufacturing requirements.
Dead Shaft
- Bearings are installed INSIDE the body
- Inside bearings mean minimizing roller deflection
- Less expensive
- Lower rolling inertia
Live Shaft
- Shaft ends are fixed to the roller body
- Self-aligning bearings can be used
- Withstands harsher and high-temperature environments
- Holds up to higher workloads
-
