This is an Optibelt Alpha Flex timing belt with the part number 100 AT5 / 2900 AFX. The AT5 profile and 2900 mm length are the two figures that identify it on a drive, so a quick check against the old belt's back marking is usually all it takes to confirm the match.
The AT5 profile is a synchronous belt profile, and the 5 mm pitch is the distance from one tooth center to the next. The 2900 mm length is the belt's length as listed. When you read a belt for replacement, the profile and the length are what let you compare one belt with another, and they are the first things we ask for when you send a quote request.
The Alpha Flex series from Optibelt covers this timing belt in the AT5 profile. If you are working from a drive that uses this size, note the part number exactly as it appears: 100 AT5 / 2900 AFX. Send that number and we will confirm the belt against it.
For a quote, send the part number 100 AT5 / 2900 AFX by WhatsApp or email, along with the quantity you need. If you have the old belt in hand, a photo of the back marking helps us confirm the profile and length before we reply.
