Timing Belt Pulleys and Sprockets by Martin Sprockets Inc. are manufactured to the closest specifications with minimum tooth-to-groove clearance for dependable performance on a wide range of drive systems.
Our Timing Belt Pulleys have evenly spaced axial grooves cut in their periphery. This ensures correct, positive engagement with the mating teeth of the belt. Each pulley is designed so that the teeth of the timing belts enter and leave the grooves with negligible friction. Resulting in a reduction in belt wear and extended belt lifetime.
We offer a range of Timing Pulleys with a trapezoidal tooth profile such as the XL, L, H and XH styles.
Our pulleys are made in five stock pitches to handle a wide range of loads, speeds and applications at the highest possible efﬁciencies. The circular pitch is a basic consideration in the selection of timing pulleys as with gear and chain drives.
Bushings are priced separately and must be added to pulley price.
