ALUMINUM ROLLERS

Used on an exceptionally wide range of web guiding applications, Aluminum Idler Rollers provide exceptional performance while possessing nearly half the weight of steel.  

This type of idler roller is best suited for web guide applications with low web tensions, less web material, and minimal web wrap.

We create both Dead Shaft and Live Shaft Aluminum Idler Rollers. Both types can be customized with air-entrainment grooves, hard coat anodizing, cantilevering, bearings inserts, cork, plasma, and rubber coverings. 

Dead Shaft Aluminum Idler Rolls

• 6061-T6 aluminum 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 in. or 0.0005 in/ft of face length
• Low-Friction ER style bearings

Live Shaft Aluminum Idler Rolls

• 6061-T6 aluminum 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 in. or 0.0005 in/ft of face length
• Journal Material 1018 Carbon Steel
• Journal run out to roll O.D. within 0.003 in.

 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
