If you have a system where you need to transmit power from one shaft to another, but it is undesirable to connect them directly, it is important to use an idler. The idlers are part of sprockets
designed to freely spin on bearings in order to help control slack in the running chain. Note that when using sprockets, idlers do not affect the power transmission ratio. Instead, the gear ratio is only dependent on the teeth number in the driven and driving shafts
. No matter whether the idler is small or larger, it helps to maintain surface speed.Like sprockets, idlers are designed using high strength materials such as carbon steel and cast iron. However, it is possible to find some idlers made using polyamide depending on the application.
