The Optibelt 100 / 5M 4000 AFX is an Alpha Flex timing belt in HTD 5M profile, with a 4000 mm length and a 5 mm pitch. When you need to replace one, the marking on the back of the old belt is the fastest way to confirm you are ordering the same thing.
Read that marking carefully before you order. The numbers and letters printed on the back identify the profile and the length, and on a worn belt the print can be faint, so clean the surface and check it in good light. Photograph the marking as it sits on the belt, then compare it against the profile and length shown on this page. If the print is gone, measure across the belt width and confirm the tooth profile and pitch from the pulley instead.
This belt is an HTD 5M profile with a 5 mm pitch and a 4000 mm length. Send us the full marking from your old belt, along with the quantity you need, and we will confirm the match. If the exact marking is no longer legible or the belt has been superseded, our team can review the details you send and suggest an equivalent so the drive keeps running.

Frequently asked questions
- How do I identify the belt I am replacing?
- Look at the marking printed on the back of the old belt. Note the profile and length exactly as they appear, and send that marking to us with your quote request. If the print has worn off, check the pulley tooth profile and pitch and measure the belt length.
- What does this belt's marking tell me?
- The marking on this belt identifies it as an Optibelt Alpha Flex timing belt in HTD 5M profile, with a 4000 mm length and a 5 mm pitch. Those are the values to match against the belt you are removing.
- What should I send to get a quote?
- Send the part number or the full marking from the old belt, the quantity you need, and any details about the drive it runs on. A photo of the marking helps us confirm the profile and length before we reply.
