The Timing belt is a type of flat belt with integral teeth. Such belts are used for power transmission or to interchange rotary motion and linear motion, where either high loads or maintaining a specific drive ratio are important. A common non-automotive application is in linear positioning systems. A timing belt is typically rubber with high-tensile fibres (e.g. fiberglass or Twaron / Kevlar) running the length of the belt.
