The Optibelt 16 AT5 / 1800 AFX is an Alpha Flex timing belt with an AT5 profile, an 1800 mm length and a 5 mm pitch. Before you fit it, inspect the drive and the sheaves so the new belt runs on clean, true surfaces.
Check the sheaves for worn grooves, burrs, corrosion and built-up debris, and confirm they are aligned and correctly tensioned. A drive that is out of alignment or has damaged sheaves will shorten the life of any timing belt, including this one.
Confirm the marking on the back of the old belt matches the Optibelt 16 AT5 / 1800 AFX: AT5 profile, 1800 mm length, 5 mm pitch. If the drive has been modified or the old belt is unreadable, measure the sheave pitch and the belt length and send those details with your request.
Send the part number, the quantity you need and any drive details by WhatsApp or email. We carry the Optibelt Alpha Flex line and can help confirm the right belt or suggest an equivalent based on your application.
