 "sheet_text": "T5 and AT5 endless timing belts (Gates PU-T5, PU-AT5): standard lengths 150 to 1500 mm with tooth counts — dimension sheet\nSource: Xem Studio, https://xemstudio.com/objects/pu-t5-at5-belt-lengths/  (sheet CC BY 4.0)\nBasis: Gates Synchro-Power catalog (PU-T5, PU-AT5 endless length tables); teeth = length / 5\nCatalog version: 2026-10-20\n\nSizes: see table below\n- Gates Synchro-Power polyurethane endless belts: the catalog pages read (62 to 65) give endless length tables for PU-T5 (5 mm pitch, trapezoidal) and PU-AT5 (5 mm pitch, AT profile). 66 T5 lengths from 150 to 1380 mm and 25 AT5 lengths from 225 to 1500 mm, each with teeth (length / 5, equal to the printed teeth on every spot check).\n- T5 and AT5 are not interchangeable: AT5 is a wider, stiffer tooth with a different flank angle. The profile table on the timing-belt-profiles page has both.\n- These are polyurethane endless (moulded) lengths; steel-cord rubber T5 belts from other makers share the same 5 mm pitch rule.\n- The Gates pages give no belt widths in the table read.
