Timing pulleys Recommended special constructions Construction OB Construction EB Construction ZB Construction OBN Construction EBN Construction ZBN Materials Steel, grey cast iron, aluminium; other materials available on request Do NOT use cast iron for speeds > 30 m/s anymore! Bores All timing pulleys are pilot bored. On request they can be finish bored to DIN H7 tolerance. Explanation of the abbreviations OB = without flanges EB = one flange ZB = two flanges OBN = without flanges, with hub EBN = one flange, with hub ZBN = two flanges, with hub 63
Permissible variation in tooth pitch The permissible variations in tooth pitch between two consecutive teeth and for the sum of the variations within a 90° arc of a pulley are shown in the following table. These tolerances indicate the distance between the corresponding points on the right or the left flank of consecutive teeth. 64 Outside diameter d a [mm] ≤ 25 > 25 ≤ 50 > 50 ≤ 100 > 100 ≤ 175 > 175 ≤ 300 > 300 ≤ 500 > 500 Outside diameter da Permissible variation [mm] [mm] ≤ 25 > 25 ≤ 50 > 50 ≤ 100 > 100 ≤ 175 > 175 ≤ 300 > 300 ≤ 500 > 500 between two consecutive teeth Permissible variation in tooth pitch [mm] Permissible variation of the outside diameter Timing pulleys Dimensions and tolerances + 0.05 0 + 0.07 0 + 0.10 0 + 0.13 0 + 0.15 0 + 0.18 0 + 0.20 0 sum within a 90° arc 0.03 0.06 0.03 0.09 0.03 0.10 0.03 0.13 0.03 0.15 0.03 0.18 0.03 0.20 Pulley width Type Pulley Nominal Smallest pulley width width pulley with without designation width flanges b f* flanges [mm] [mm] [mm] [mm] 3 M 6 6 7 9 9 9 10 12 15 15 17 19 5 M 9 9 10 12 15 15 17 19 25 25 27 29 8 M 20 20 22 26 30 30 34 38 50 50 54 58 85 85 90 94 14 M 40 40 47 54 55 55 63 70 85 85 95 102 115 115 126 133 170 170 180 187 *b f = Pulley width between the flanges Note The minimum width b for pulleys without flanges can be reduced, if there is no side wobble or run out; however, it may not fall below the minimum width bf for pulleys with flanges.
