The Optibelt 50 / 5M 8000 AFX is an Alpha Flex timing belt with an HTD 5M profile and an 8000 mm length. When you need to replace a belt, the marking on its back is the most reliable starting point. This page covers what that marking tells you and how to request a quote for this exact belt.

Read the old belt before you remove it. The back of the belt carries the part number and size, and that marking is what identifies the correct replacement. For this belt, the marking is 50 / 5M 8000 AFX. The profile is HTD 5M, the length is 8000 mm, and the pitch is 5 mm. Write the marking down exactly as it appears, including any spaces or slashes, so the part number can be confirmed without guesswork.

If the marking is worn or unreadable, measure the belt and note the drive it runs on. Send the part number, the profile, and the length in millimeters to our team by WhatsApp or email. We can confirm the belt or suggest an equivalent from the brands we carry. For drives that use more than one belt, note the quantity so the set can be matched.

A timing belt replacement is also a chance to inspect the drive. Check the pulleys for wear or damage, confirm the belt tension is correct for the application, and look for any debris or fluid that could affect belt life. If the old belt failed early, mention what you found so the replacement can be reviewed against the drive conditions.
