Positive Drive Pd® XH ( 7/8" Pitch) Timing Pulleys

Continental® XH Series 7/8" (Pitch 0.875) Timing pulleys are available in a wide range of stock widths 2", 3", 4" diameters. The pulleys in this series come (MPB) minimum plain bore and will need to be machined to fit prefered shaft size, set screws and keyway. Flanged pulleys because timing belts have an inherent, gentle side thrust, it is necessary to use at least one flanged pulley to prevent the belt from riding off. Generally, for economics, the smaller pulley in each drive is flanged. In this section we offer steel pulleys.
