The Optibelt 25 / 8M 4200 AFX is an Alpha Flex timing belt with an HTD 8M profile, a 4200 mm length and an 8 mm pitch. If you are replacing a belt on an existing drive, the marking on the back of the old belt is the fastest way to identify what you need. Read it before you order, then match it to this listing.
The back of a worn timing belt usually carries the profile, the length and the manufacturer's part number. On this Optibelt belt, the marking identifies an HTD 8M profile, a 4200 mm length and an 8 mm pitch. Write the marking down exactly as it appears, including any numbers that come before the profile, because those characters are part of the part number.
Once you have the marking, compare it with the belt data on this page. The profile, length and pitch must match the drive you are working on. If the old belt is damaged or the marking is unreadable, measure the length and confirm the profile from the pulleys before ordering.
