Walther Flender Gruppe PolyChain Page ® GT Timing Belts PAGE 08 Models Endless design Pitches PolyChain® endless timing belts are manufactured with 8 mm and 14 mm pitches and are available in a large assortment of lengths and widths. The main dimensions of the timing belt are: Pitch – Pitch length – Width The timing belt pitch is the distance in millimeters between two adjacent tooth centres, measured on the timing belt pitch line. The pitch length is the total circumference of the timing belt in millimeters, measured on the belt pitch line. The theoretical pitch line of a PolyChain® timing belt is in the centre of the tensile member. The available timing belt lengths and standard widths are listed on pages 19 and 22. Dimensions Pitch (mm) h s t (mm) h t (mm) Width tolerances For both 8 mm and 14 mm pitches, the tolerance is ±3 % of the belt width. Length tolerances (in relation to the centre distance of axes; specified in mm) Belt length Tolerance h S (mm) 8 8 3.4 5.9 14 14 6.0 10.2 h t t up to 762 +/- 0,30 above 762 to 1016 +/- 0,33 above 1,016 to 1,270 +/- 0,38 above 1,270 to 1,524 +/- 0,41 above 1,524 to 1,778 +/- 0,43 above 1,778 +/– 0.43 mm ± 0.03 mm for every 254 mm level for 1778 mm and above To use PolyChain® timing belts with fixed centre distances of axes, please consult our application engineers. Weights per metre in kg for PolyChain® GT2 Pitch (mm) Weights per metre in kg for PolyChain® Carbon TM The weights per metre can vary slightly depending on the belt construction and the tolerance positions. The ordering designation includes the pitch, pitch length and belt width: PolyChain® GT2 Example: PC-8MGT 640 - 12 or PC-14MGT 1190 - 37 PolyChain® GT Carbon TM Example: PC-8MGT 640 - 12 Carbon or PC-14MGT 1190 - 37 Carbon Pitch (mm) Belt width (mm) 12 20 21 36 37 62 68 90 125 8 0.057 - 0.099 0.170 - 0.293 - - - 14 - 0.158 - - 0.292 - 0.536 0.709 0.985 Pitch (mm) Belt width (mm) 12 20 21 36 37 62 68 90 125 8 0.056 - 0.099 0.169 - 0.291 - - - 14 - 0.158 - - 0.292 - 0.537 0.711 0.987 Pitch length (mm) Width (mm) 8 M 640 12 14 M 1190 37
