This Optibelt Alpha Flex belt is a timing belt with an AT20 profile and a 6400 mm length. The 20 mm pitch is the spacing between tooth centers along the belt. Use these three values to confirm the belt matches your drive before you request a quote.
The AT20 profile is a synchronous tooth profile. The 6400 mm length is the belt's datum length. The 20 mm pitch is the distance from one tooth center to the next. When you read the marking on the back of an old belt, compare it with the part number 75 AT20 / 6400 AFX to confirm the profile, length and pitch match your drive.
If you are replacing a belt on a drive that uses this size, check the pulleys for worn teeth, the tensioner for smooth travel and the belt for uneven wear or missing teeth. A belt that has run out of alignment or under the wrong tension will show edge wear or a glazed backing. Correcting those conditions before installing a new belt helps the replacement run as intended.
To request a quote, send the part number 75 AT20 / 6400 AFX by WhatsApp or email. If you are not sure of the number, send the marking from the back of the old belt and the tooth count, or a photo of the belt and the drive. We carry Optibelt and can help confirm the right belt or suggest an equivalent.
