This is the Optibelt Alpha Flex timing belt with code 85 / 8M 8200 AFX. It uses the HTD 8M profile with an 8 mm pitch and a length of 8200 mm. If you are replacing a belt on a large synchronous drive, those two values are what you match first.
The profile and length are the identifying data here. HTD 8M sets the tooth shape and the 8 mm pitch; 8200 mm is the datum length around the belt. On a long-center drive, a belt that is close but not exact will not tension correctly, so confirm both figures against the belt you are removing.
The marking on the back of the old belt is the fastest reference. Look for the Optibelt name and the code 85 / 8M 8200 AFX, and read the profile and length from the same line. If the marking is worn or the belt is damaged, measure the length and count the teeth to confirm the HTD 8M profile before ordering.
We carry Optibelt belts and quote by part number. Send the code, the quantity, and a photo of the back marking if it is legible, and we will confirm the belt or suggest an equivalent. For drives running more than one belt, list every position so the set can be matched.
For maintenance and purchasing teams, quoting by part number avoids the back-and-forth of profile and length questions. Include the application and any drive details you have so we can check the belt against the equipment.

Frequently asked questions
- What do the profile and length tell me about this belt?

- How do I confirm this is the right belt?
- Read the marking on the back of the belt you are replacing and compare it to the code 85 / 8M 8200 AFX. If the marking is gone, measure the length and confirm the HTD 8M profile.
- What should I send to get a quote?
- Send the part number 85 / 8M 8200 AFX, the quantity you need, and a photo of the back marking if it is readable. If you are replacing a set, include the number of belts on the drive.
