Idler sprockets are a flat hubless sprocket, with a sealed bearing that allows the sprocket to rotate freely. They can compensate for chain stretch resulting from operation and provide smoother system running under high loads and speeds. Idlers are normally mounted in a fixed position on a fixed shaft or attached to a tensioner arm.
