The Optibelt 50 / 8M 6400 AFX is a timing belt from the Alpha Flex series with an HTD 8M profile, a 6400 mm length and an 8 mm pitch. When you need to match an existing drive, the marking on the back of the old belt is the most reliable starting point. Read it carefully and note the full part number, profile and length before you request a quote.
The back of a worn timing belt usually carries the part number, the profile and the length. On this Optibelt belt, the marking identifies it as 50 / 8M 6400 AFX, an Alpha Flex timing belt with an HTD 8M profile and a length of 6400 mm. The 8 mm pitch is part of the profile designation. If the old marking is faded or worn away, measure what you can and send clear photos of the belt and the drive so we can help confirm the correct part.
Because timing belts are often replaced as part of scheduled maintenance, it pays to inspect the drive at the same time. Check the pulleys for wear, make sure the belt tracks correctly and look for any signs of damage that could affect the replacement. If the drive uses more than one belt, replacing them as a set helps keep the drive running smoothly.
We carry the Optibelt 50 / 8M 6400 AFX and can help you confirm it is the right belt for your application. Send the part number, the profile and the length by WhatsApp or email, and our team will reply promptly. If you need an equivalent, let us know what the old belt says and we will suggest a suitable match.
