In industrial machinery, robotics, and automotive engines, HTD timing belts transfer high torque. Timing belts, also called toothed belts or timing belts, provide high power transmission, low noise, and oil and chemical resistance. High Torque Drive is an acronym for High Torque Drive. HTD offers tooth profiles of 3M, 5M, 8M, 14M, and 20M. Trapezoidal belts are less load-bearing than rubber timing belts with HTD. HTD belts perform better when there is more contact area between the belt and the pulley. To learn more, please visit: https://www.zzr-parts.com/htd-timing-belt/. Phone: 734-427-7700
