Timing Belts are one of the most important part of Power Transmission drives. Timing Belt can be best described as Belt with integrally moulded teeth on its inside which makes positive engagement with axially grooved pulley. Timing Belt is also known as synchronous Belt or positive-drive Belt. Timing Belt drive is not considered as a substitute or replacement to other modes of Belt drives.Timing Belts exhibit important properties such as fixed speed ratio, no re-tensioning after installation, low maintenance with wide variety of power transmission capacities and drive speeds.
