The Optibelt 50 AT5 / 1700 AFX is an Alpha Flex timing belt built on the AT5 profile with a 1700 mm length and a 5 mm pitch. The profile and length are the two figures that decide whether this belt drops onto your drive, so read both off the old belt before you order.
Start with the profile. AT5 identifies the tooth form and the 5 mm pitch, which is the center-to-center distance between adjacent teeth. A drive machined for AT5 takes an AT5 belt; a different profile will not seat correctly in the pulley grooves no matter how close the length looks.
Then confirm the length. This belt is listed at 1700 mm. On a timing drive, length has to match the pulley count and the center distances, so compare the figure against the marking on the back of the belt you are replacing rather than against a measurement taken on a worn belt.
If the marking is worn off or the belt has already been discarded, send us the part number you have, along with the profile and length you can read, and our team will confirm the belt or suggest an equivalent. We supply maintenance, engineering and purchasing teams across the United States, Canada, Mexico and South America, and quotes are handled by WhatsApp or email.

Frequently asked questions
- What do the AT5 profile and 5 mm pitch mean for fit?
- AT5 is the tooth profile and 5 mm is the pitch, the distance between adjacent teeth. Both are set by the pulley grooves, so a belt with a different profile or pitch will not run correctly on the same drive.
- How do I confirm the 1700 mm length?
- Check the marking on the back of the belt you are replacing and match it to 1700 mm. That is more reliable than measuring a used belt, which may have stretched or worn.
- What should I send to request a quote?
- Send the part number 50 AT5 / 1700 AFX, or the profile and length you can read from the old belt, by WhatsApp or email. Our team replies promptly and can confirm the belt or suggest an equivalent.
