Timing pulleys mate with same-pitch timing belts in synchronous drives. Timing pulleys are used in power transmission systems where maintenance of speed ratio is an important design consideration. These synchronous belt drive systems are durable, highly efficient, and suitable for many different applications. Metric pitch timing pulleys have a spacing or pitch based on millimeter (mm) measurements and trapezoidal or curvilinear, toothed form. Timing Belts. Spark timing can be advanced a few degrees for some additional low speed torque, and the engine is less prone to detonation, which can be a plus in turbocharged, supercharged or nitrous applications. This is used for driving multiple pulleys. H Series Bushed Bore Timing Belt Pulleys For Use With: 1 in Wide Belt, 1/2 in Pitch, sorted by Number of Grooves - Timing Belt Pulleys, ascending.
