Summary

Lightweight Aluminum Idler Rollers - Overview

Made from ¼" wall 6061-T6 aluminum tube, Epoch Lightweight Aluminum Dead Shaft Idlers are gaining in popularity. Made for lower web tension applications, these rolls have less weight and less rolling inertia than standard aluminum idlers.

All other aspects of these rolls are the same as our standard aluminum idlers. Made with special low-drag ER style bearings for solid thru shafts, these idlers are dynamically balanced to ISO grade G6.3. Each roll is machined to precision tolerances and has a 32 RMS surface finish across the face. If a hard surface is required to prevent grooving, hard coat anodizing is a popular surface treatment we provide.

Advantages:

• 35% - 45% lower rolling inertia than comparable standard aluminum idlers
• Moderately priced, slightly higher than comparable standard aluminum idlers
• Corrosion resistance higher than steel
• Easy to custom coat and surface treat
• Solid steel thru shafts allow for heavier loading than other lightweight idlers
