Stock Timing Pulleys STOCK TIMING PULLEYS 1/5" - 7/8" PITCH QD, TAPER BUSHED AND STOCK BORE Stock Bore Pitch (Inches) Pulley Designation 1/5" XL (Extra Light) 3/8" L (Light) 1/2" H (Heavy) 7/8" XH (Extra Heavy) Taper Bushed QD Timing Pulleys are manufactured to extremely close specifications and are stocked in minimum plain bore, Taper Bushed and QD bushed styles depending on size and pitch. See tables for stock pulley types. Bushings are priced separately and must be added to pulley price. Illustrations below indicate stock pulley construction type listed in tables. Type DF Type CF Type D Type C Type AF Type KF Type A Type G Type H Type J “F” designation in pulley type means pulley is flanged. When drive center distance is eight times the diameter of the smaller pulley or when drive is operating on vertical shafts, both pulleys should be flanged.

Timing Pulley Terminology Timing belts and pulleys in order to handle a wide range of loads, speeds and applications at highest possible efficiencies are made in five stock pitches. Circular pitch (usually referred to as pitch) is a basic consideration in the selection of timing pulleys as with gear and chain drives. Pitch is the distance between groove centers

and is measured on the pulley pitch circle. On the belt, pitch is the distance between tooth centers and is measured on the pitch line of the belt. Pitch (Circular Pitch) Belt Pitch Line Belt Tooth Pitc Diam h eter The pitch line of the belt is located within the tension member and coincides with the pitch circle of the pulley mating with it. Any timing belt must be run with pulleys of the same pitch. A belt of one pitch cannot be used successfully with pulleys of a different pitch. de Outsi r ete m a i D Pulley Groove Pitch Line Differential TIMING BELT TERMINOLOGY E C F D B TIMING PULLEY TERMINOLOGY N O G L Pitch of Teeth Depth of Teeth Width at Bottom of Teeth Pressure Angle Radius at Bottom of Teeth Radius at Top of Teeth Pitch Line Differential Belt P.L = “A” X Total No of Teeth in Belt L M S A A B C D E F G P L L R L L M N O P R S Circular Pitch of Groove Minimum Depth of Groove, Including Clearance Width of Groove at Minimum Depth, Including

These pulleys are designed so that the teeth of the belt enter and leave the grooves with negligible friction. All pulleys, stock and made-to-order, have minimum tooth-to-groove clearance (backlash). The pulley’s pitch diameter will always be greater than its outside diameter. Pulleys are available in a wide range of stock widths and diameters.

Flanged Pulleys Pulley Diameters 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 economy, the smaller pulley in each drive is flanged. However, when the center distance is greater than eight times the diameter of the smaller pulley on drive ratios less than 3 to 1, or when the drive is operated on other than horizontal shafts both pulleys should be flanged. When a drive has three pulleys, at least two should be flanged. If the drive has more than three pulleys, every other pulley should be flanged. Stock timing belts should not be used over pulley diameters less than those recommended above without expecting some reduction in belt life. This reduced belt life is the result of

flex fatigue of the steel tension members in the belt. If pulleys smaller than recommended must be used, the use of special timing belts should be considered.
