Carbon Fiber Idler Rollers
Carbon Fiber Idler Rollers
Carbon Fiber Idler Rollers
Double E Group composite Idlers are made using 1/8" wall (3/16" in larger sizes), carbon fiber/epoxy matrix composite. The tube has nearly double the stiffness-to-weight ratio of aluminum and provides unparalleled low rotating inertia.
Double E Group carbon fiber composite idlers offer superior performance. These idlers are ideal for running wide, light weight webs at higher critical speeds, and are the lightest standard idlers Double E Group manufactures.
These idlers are dynamically balanced to ISO grade G6.3. Each roll is machined to precision tolerances and has a 63 RMS surface finish across the face.
Advantages:
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.

Specifications - 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.
