The Optibelt 100 / H 670 AFX is an Alpha Flex timing belt with an H profile and a length of 1701.8 mm. When you are replacing a belt, the fastest way to confirm the match is to compare these two figures directly against the belt you are removing. We carry this belt for maintenance, engineering and purchasing teams across the United States, Canada, Mexico and South America.

A timing belt is matched by profile and length before anything else. The H profile on this Optibelt Alpha Flex belt determines the tooth shape and pitch, while 1701.8 mm is the datum length. If the old belt is still readable, check the marking on the back: it should show the same profile and a length that corresponds to 1701.8 mm. If the marking is worn off, measure the old belt or count the teeth and compare.

Do not rely on a part number alone if the belt has been replaced before. A previous substitution may have used a different profile or length that happened to fit. Confirm the H profile and the 1701.8 mm length against the drive you are working on, and check the pulleys for wear or debris at the same time. If the drive runs more than one belt, replace the set together so the load stays even.

If you are unsure, send us the part number 100 / H 670 AFX, or the marking from the old belt, by WhatsApp or email. Our team replies promptly and can help confirm the right belt or suggest an equivalent. We serve customers throughout the United States, Canada, Mexico and South America.
