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 grooving, hard anodizing is a popular surface treatment we provide.
Standard Aluminum Dead Shaft Idlers are made with special low-drag ER style bearings for solid thru shafts. Through shafts are available in either 300 series stainless steel or 1045 mild steel.
Standard Aluminum Live Shaft Idlers are made with 12L14 steel journals (shafts). Journal dimensions are custom made to your application.
Aluminum Dead Shaft Idlers
Aluminum Live Shaft Idlers
Epoch standard aluminum dead shaft idler rollers have a fixed central thru shaft (axle). Bearings allow the roller body to spin on the fixed shaft.
Epoch standard aluminum live shaft idlers rotate with their journals (axle) as a single unit.
Made from ¼" wall 6061-T6 aluminum tube, Epoch lightweight aluminum idlers have less weight and less rolling inertia than standard aluminum idlers.
Epoch carbon fiber composite Idlers have nearly double the stiffness-to-weight ratio of aluminum and provides unparalleled low rotating inertia.
Made from DOM steel tubing, Epoch steel idlers offer high strength and performance. Steel idlers are well suited for high to medium loading applications.
