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. Thru 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.
