OPTIBELT 15 / 5M 4000 AFX belongs to timing belt, part of our Power transmission range. Tell us how many you need by WhatsApp or email and we'll get back to you promptly with a quote for 15 / 5M 4000 AFX and any equivalents.
The Optibelt 15 / 5M 4000 AFX is a timing belt in the Alpha Flex series. Its HTD 5M profile and 4000 mm length identify the drive it fits, so you can match the belt to the pulley groove and center distance on your equipment.
The 5M profile is an HTD tooth form with a 5 mm pitch. That pitch fixes the spacing between the teeth and the matching pulley grooves, so the belt must be specified as HTD 5M rather than by width or by an older profile. The 4000 mm length is the datum length for the belt, and it sets the center distance range the drive can cover.
When you request a quote, send the full part number 15 / 5M 4000 AFX along with the belt marking from the old part. If the marking is worn, note the profile and length from the drive documentation. We carry Optibelt belts and can confirm the belt or suggest an equivalent from the same profile and length.
For drives that run more than one belt, replace the set together so the load stays shared evenly. Inspect the pulleys for worn grooves, check the tension against the drive manufacturer's specification, and confirm the belt sits correctly in the grooves before returning the drive to service.

Frequently asked questions
- What do the profile and length tell me about this belt?
- The HTD 5M profile and 5 mm pitch tell you the belt fits pulleys with the same tooth form and groove spacing. The 4000 mm length is the datum length, which sets the center distance the drive can cover. Both values must match the drive before you order.
- How do I request a quote for the 15 / 5M 4000 AFX?
- Send the part number 15 / 5M 4000 AFX by WhatsApp or email. If you have the old belt, include a photo of the marking on the back. We reply promptly and can confirm the belt or suggest an equivalent.
- Should I replace more than one belt at the same time?
- On drives that use multiple belts, replace the full set together. Mixing a new belt with worn belts can cause uneven load sharing. Check pulley grooves and set tension to the drive manufacturer's specification.
