Type A Idler Sprockets

Type A idler sprockets are specialized roller chain sprockets designed to maintain proper chain tension and alignment in power transmission systems. Featuring a simple, flat profile without a hub or teeth, these sprockets are used in various industrial applications to reduce chain wear, minimize noise, and improve overall system efficiency. Selection of a Type A idler sprocket should consider factors such as chain size, pitch, and required load capacity.
