On a typical roller chain drive application, there is a drive sprocket and idler sprockets. Idler sprockets are designed in conveyor applications to essentially “carry” or guide a roller chain in a straight line, around a bend, or in a complete 360-degree directional change. If an idler sprocket fails while in use the result can be catastrophic depending on the application. Because of this it is always important to monitor the status of your idler sprockets and use a high-quality sprocket.
