Epoch's stainless steel Idlers use type 304 stainless steel tubing. Stainless steel 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.
These Stainless Steel Idlers are used in corrosive environments and high moisture applications. Since stainless steel is more abrasive resistant than mild steel, these idlers are also used where abrasive elements can damage normal steel idler rolls. Typical applications for Stainless Steel Idlers include food and medical grade applications. Corrosion resistant bearings are available upon request.
Like steel Idlers, stainless steel Idlers are well suited for high to medium loading applications. When running long webs at high speeds and tensions, Stainless Steel Idlers have a higher first critical speed than aluminum rolls due to their superior stiffness. Each roll is machined to precision tolerances, has a 32 RMS surface finish across the face, and is dynamically balanced to ISO grade G6.3.
Stainless steel live shaft Idlers are made with 300 stainless steel journals (shafts). Journal dimensions are custom made to your application.
