The Optibelt 100 AT20 / 9800 AFX is an Alpha Flex timing belt with an AT20 profile, a 9800 mm length and a 20 mm pitch. Before you fit it, inspect the drive and the sheaves so the new belt runs true from the start.
Check the sheaves for worn grooves, burrs or buildup that can damage the belt. Confirm the shafts turn freely and that the bearings have no play. Verify alignment and tensioner movement, because a drive that is out of line will shorten the life of any timing belt.
The AT20 profile and 9800 mm length identify this belt. Read the marking on the back of the old belt and compare it with the part number on this page. If the marking matches, the 100 AT20 / 9800 AFX is the correct replacement.
Send the part number 100 AT20 / 9800 AFX by WhatsApp or email to request a quote. If you are unsure about the profile or length, include the old belt marking and a photo of the drive, and we will help confirm the right belt or suggest an equivalent.
