Webex Standard Stainless Steel Idlers are ideal for use in aggressive environments where corrosive or abrasive elements can damage normal steel idlers. These Corrosion Resistant (CR) idlers are also specified frequently for clean room, food grade and medical applications, or wherever high moisture conditions exist.

Stainless Steel Idlers employ the same high-performance alloy steel bearings used in our Standard Steel Idlers. Consult the Webex customer support team for special bearing needs, including clean room bearing shields.

Like steel rolls, Stainless Steel Idlers also have the strength to withstand substantial loading from nips or web tension. They perform well in elevated temperatures up to 350ºF.

For greater wear-resistance, Stainless Steel Idlers can be readily plated with plasma coating, nickel or chrome.

To ensure maximum performance over a wide range of conditions, Webex Stainless Steel Dead Shaft Idlers are constructed with 304 stainless steel. Stainless steel shafts also also available. For more aggressive environments, other stainless steel grades are available.
