The Optibelt 25 AT20 / 8600 AFX is an Alpha Flex timing belt with an AT20 profile, an 8600 mm length and a 20 mm pitch. Before a belt this size goes on, the drive itself is worth a look. Send us the part number and we will quote it.
A long synchronous belt only runs as well as the drive it sits on. Check the sheaves for worn teeth, corrosion, buildup in the grooves and any damage from a previous belt failure. Confirm the two shafts are still parallel and that the sheave flanges are not rubbing. On a drive of this length, a small alignment error shows up as edge wear long before the belt is worn out.
Inspect the tensioning arrangement as well. Idlers and tensioners should turn freely and run true, and any worn bearing or flat spot should be dealt with before the new belt is fitted. Fit the belt without prying it over a flange, then tension it to the drive manufacturer's specification and recheck after the first run-in period.
