This Optibelt Alpha Flex belt is a timing belt with profile AT20 and a length of 6400 mm. The 20 mm pitch is stated in the code and in the profile data, so you can match it directly against your drive specification.
The profile and length are the two figures that decide fit on a synchronous drive. AT20 identifies the tooth profile, and 6400 mm is the datum length. The code 100 AT20 / 6400 AFX also carries the 20 mm pitch, which agrees with the profile field. Check these against the marking on the belt you are replacing before you order.
If the old belt is worn or the back marking is unreadable, send the part number you have, the profile and the length. We carry the Optibelt Alpha Flex line and can confirm the belt or suggest an equivalent from the same size listing. Photos of the drive and the belt back help us verify the profile and pitch.
For a quote, message us on WhatsApp or by email with the code 100 AT20 / 6400 AFX and the quantity you need. If you are replacing a set, include the number of belts on the drive so we can quote the full set.
