The Optibelt 25 AT10K13 / 9000 AFX is a timing belt in the Alpha Flex series, built to the AT10 profile with a 10 mm pitch and a 9000 mm length. When you are replacing a belt, match these three values to the belt you are taking off: profile, pitch, and length. That is the fastest way to confirm you are ordering the same belt.
Start with the marking on the back of the old belt. Read the profile and the length, then compare them to the AT10 profile and 9000 mm length of this Optibelt belt. A belt with the same profile but a different length will not fit the drive, so check both numbers before you order.
If the marking is worn off, measure the old belt instead. Confirm the tooth profile matches AT10 and the pitch measures 10 mm, then measure the length. For a drive that runs more than one belt, replace the full set at the same time so the belts share the load evenly.
If you are unsure whether this is the correct replacement, send the part number from the old belt, the profile, the length in mm, and the pitch to our team by WhatsApp or email. We carry Optibelt belts and can confirm the right belt or suggest an equivalent.

Frequently asked questions
- How do I match this belt to the one I am replacing?
- Compare the profile, pitch, and length. This belt is AT10 profile, 10 mm pitch, and 9000 mm long. If your old belt has the same three values, it is the same size.
- What should I send for a quote?
- Send the part number 25 AT10K13 / 9000 AFX, or the profile, length, and pitch from your old belt, by WhatsApp or email. Our team will confirm the belt and reply with a quote.
- Can I replace just one belt on a multi-belt drive?
- Replace the full set at the same time. Belts that have run together wear together, and mixing a new belt with used ones can cause uneven load sharing.
