Notes

  • 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).
  • 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.
  • These are polyurethane endless (moulded) lengths; steel-cord rubber T5 belts from other makers share the same 5 mm pitch rule.
  • The Gates pages give no belt widths in the table read. No files.

What T5 belt lengths are standard?

From 150 mm (30 teeth) to 1380 mm (276 teeth); see the table for all lengths in Gates' PU-T5 list.

Is AT5 the same as T5?

No: same 5 mm pitch, different tooth profile; the two do not run in each other's pulleys.
