GT2 (2GT) closed-loop timing belts, 6 mm wide: standard lengths and tooth counts, 110 to 1524 mm — dimension sheet Source: Xem Studio, https://xemstudio.com/objects/gt2-closed-loop-belt-lengths/ (sheet CC BY 4.0) Basis: Two shop lists: HC Maschinentechnik (19 lengths with teeth) and Tinytronics (9 lengths); teeth = length / 2 Catalog version: 2026-10-20 Sizes: see table below - Closed-loop (endless, welded or moulded) GT2 / 2GT belts, 2 mm pitch, 6 mm wide, in the lengths two shops list. Length is the pitch length (the cord line), so teeth = length / 2: HC Maschinentechnik prints the teeth for its 19 lengths and they equal length / 2, except that its description table lists 500 mm as 225 teeth while its length dropdown says 250 (500 / 2 = 250, which the table uses). Tinytronics prints lengths only (110, 158, 200, 280, 300, 320, 400, 610, 852 mm), so its teeth are length / 2 and not read from the shop. - These are shop stock lists, not a Gates catalog: other closed-loop lengths exist (the 2MR family in Gates' own catalog was not readable). 6 mm is the width both lists give; 9 and 10 mm GT2 loops exist but no table was read for them. - Two equal pulleys of N teeth and a belt of pitch length L: L = 2 C + pi x PD = 2 C + 2 N mm, so the centre distance is C = (L − 2 N) / 2 mm (pulley PD = N x 2 / pi). - No files: a closed loop is a length and a pitch, nothing more to model. pitch length, mm teeth (length / 2) length, in listed by 110 55 4.33 Tinytronics 122 61 4.80 HC Maschinentechnik 140 70 5.51 HC Maschinentechnik 158 79 6.22 both shops 180 90 7.09 HC Maschinentechnik 200 100 7.87 both shops 232 116 9.13 HC Maschinentechnik 260 130 10.24 HC Maschinentechnik 280 140 11.02 Tinytronics 300 150 11.81 Tinytronics 320 160 12.60 both shops 350 175 13.78 HC Maschinentechnik 400 200 15.75 both shops 450 225 17.72 HC Maschinentechnik 500 250 19.69 HC Maschinentechnik 600 300 23.62 HC Maschinentechnik 610 305 24.02 Tinytronics 760 380 29.92 HC Maschinentechnik 852 426 33.54 Tinytronics 860 430 33.86 HC Maschinentechnik 976 488 38.43 HC Maschinentechnik 1220 610 48.03 HC Maschinentechnik 1360 680 53.54 HC Maschinentechnik 1524 762 60.00 HC Maschinentechnik Files elsewhere (not hosted by Xem Studio; license as stated by the publisher): - HC Maschinentechnik: GT2 closed timing belt 6 mm wide: lengths and teeth (122 to 1524 mm) — web — Publisher's page; dimensions are facts — https://hc-maschinentechnik.de/GT2-Closed-timing-belt-6mm-wide - Tinytronics: GT2 timing belts 6 mm wide, closed loop: 110, 158, 200, 280, 300, 320, 400, 610, 852 mm — web — Publisher's page; dimensions are facts — https://www.tinytronics.nl/en/3d-printing/parts/timing-belts No true-size file yet: the published figures do not fix the whole shape; a measured scan is planned.
