Summary

Standard Aluminum Idler Rollers - Overview

All aluminum 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 wear, hard anodizing is available upon request.

Advantages

Lower rotating inertia than comparable steel idlers
Economic and lightweight
Natural corrosion resistance
Medium to heavy loading possible
Easy to custom coat and surface treat

Specifications

Dead Shaft

"Dead shaft" idler rollers have a bearing in the idler roll body and therefore the dead shaft (axle) remains stationary. The shaft is fixed to the machine frame in various manners.

Live Shaft

Live shaft rollers have a shaft (axle) that is fixed to the idler roll and therefore rotates with the roller body. The roller bearing is mounted to the machine frame, generally a pillow block or flange mounted bearing.
