This is an Optibelt Alpha Flex timing belt with the code 75 T20 / 6400 AFX. Its profile is T20 and its length is 6400 mm, on a 20 mm pitch. If you are replacing a belt on a drive that runs this profile and length, this page gives you the two numbers that matter most when you match a belt.
The profile sets how the belt sits in the pulley grooves and how the teeth engage, so T20 has to match the pulleys on the drive. The length is the second check: 6400 mm is what the drive is built around, and a belt of another length will not tension or time correctly even if the profile looks right. Read both figures off the old belt before you order.
The code on the back of the belt is the fastest way to confirm what you are running. Compare it to 75 T20 / 6400 AFX, along with the profile and length, and note the drive it came off. If the marking is worn or unreadable, send us the pulley details and the belt's profile and length and we will help you confirm the right belt or suggest an equivalent.
We carry this belt and quote by part number. Send the code 75 T20 / 6400 AFX by WhatsApp or email and the team will reply promptly. On drives that run more than one belt, order the full set so the belts wear and tension together.

Frequently asked questions
- What do the profile and length tell me about this belt?
- The T20 profile tells you the tooth shape and the 20 mm pitch it runs on, so it must match your pulleys. The 6400 mm length is the belt's length, and it has to match the drive's center distance and take-up. Both are listed together in the code 75 T20 / 6400 AFX.
- How do I confirm this is the belt on my drive?
- Read the marking on the back of the old belt and compare it with 75 T20 / 6400 AFX. Check the profile and the length as well. If the marking has worn off, send us the pulley data and the profile and length you measured.
