This Optibelt Alpha Flex belt is a timing belt with an AT5 profile and a 9800 mm length. The 5 mm pitch and the part number 25 AT5K6 / 9800 AFX identify it for drives that require an AT5 synchronous profile in this length.
When you select by profile and length, the AT5 profile sets the tooth geometry and the 9800 mm length sets the belt's reach around the pulleys. The 5 mm pitch is the distance from one tooth center to the next. These three values are the core selection data for this belt.
If you are matching an existing belt, read the marking on the back of the old belt and compare it with 25 AT5K6 / 9800 AFX. The profile and length must agree before you install a replacement.
For a quote, send the part number 25 AT5K6 / 9800 AFX, the profile AT5, and the length 9800 mm. If you have the old belt, include a photo of the back marking. We carry the Optibelt Alpha Flex line and can confirm the belt or suggest an equivalent.
