Idlers

An idler is a gear-shaped part that rotates as a chain moves. It is used in various machines, such as automobile engines, compressors, and power generators that transmit power using belts and chains. However, idlers themselves are idle gears that do not transmit power to gears or shafts. By using an idler, it is possible to maintain suitable transmission tension and stable movement. In addition, there are gear-shaped sprockets that transmit rotation, idler pins for fixing the idler with nuts and screws, tensioners for adjusting the slackness and friction of the chain, etc., and guide rollers for sliding doors. In particular, there are three types of sprockets: A type on a flat plate without a boss, B type with a boss on one side, and C type with a boss on both sides.
