Classical Timing Belt Pulleys feature uniformly spaced grooves cut in their periphery. This design enables a correct and positive attachment with the mating teeth of the belt. The pulleys are made with close tolerances to ensure smooth concentric running.
Cross and Morse pulleys are made with the groove form to enable the teeth to enter and leave the pulley with minimal friction and little backlash. For maximum versatility in the drive selection, the pulleys are made available in various stock widths and with numerous options for the number of teeth.
