The Optibelt 400 / H 670 AFX is an Alpha Flex timing belt with an H profile and a length of 1701.8 mm. It is the belt to reference when you are replacing a synchronous drive belt and want the same profile and length as the one coming off the machine.
The most reliable way to match this belt is to read the marking on the back of the belt being replaced. Look for the part number, the profile and the length, and compare them with the H profile and 1701.8 mm length shown here. If the old belt is worn, frayed or missing its marking, measure the length and confirm the tooth profile before ordering.
A timing belt drives from tooth engagement, so the profile has to match the pulley grooves and the length has to match the pulley centers. An H profile belt at 1701.8 mm is not interchangeable with a different profile or a different length, even when the belt looks close in size. Check the pulleys for worn teeth, and check the tensioner and idler for play at the same time.
Send the part number 400 / H 670 AFX, or the marking from your old belt, by WhatsApp or email and the MR team will confirm the belt and reply with a quote. If you are unsure of the profile or the length, send a photo of the belt back and a photo of the drive, and the team can help identify what you need.
