Timing pulleys feature uniformly spaced axial grooves around their perimeter, ensuring precise and positive engagement with the corresponding teeth of the belt. These pulleys are engineered to minimize friction as the belt’s teeth enter and exit the grooves. Additionally, the pitch diameter of the pulley is always larger than its outer diameter.
H 1/2" (Pitch 0.500) timing pulleys are offered in a variety of stock widths: 1", 1-1/2", 2", and 3" diameters.
L 3/8" (Pitch 0.375) timing pulleys come in a selection of stock widths: 1/2", 3/4", and 1" diameters.
