This Optibelt Alpha Flex timing belt is identified by the code 100 / 8M 3400 AFX. It uses the HTD 8M profile with a 3400 mm length and 8 mm pitch. Use it to confirm fit on industrial synchronous drives where this profile and length are specified.

HTD 8M synchronous belts are common on industrial drives that need positive engagement rather than friction, such as conveyors, mixers, pumps and other process equipment. The 8 mm pitch and 3400 mm length make this a long-span belt, so check the drive's pulley grooves and center distance before ordering. The belt is marked 100 / 8M 3400 AFX on the back, which is the fastest way to match what is currently installed.

To confirm fit, read the full marking on the old belt, including the profile and length, and compare it to this listing. If the old belt is worn or the marking is unreadable, measure the length and check the pulley profile. Send the part number and any photos of the marking to our team by WhatsApp or email, and we will confirm the belt or suggest an equivalent.

When replacing a timing belt, inspect the pulleys for wear, check alignment and verify that the drive is locked out before removal. If the drive uses more than one belt, replace them as a set so the load stays even. After installation, check tension according to the drive manufacturer's procedure and recheck after the first run-in period.
