The Optibelt 75 / 5M 6400 AFX is an Alpha Flex timing belt with an HTD 5M profile, a 6400 mm length and a 5 mm pitch. Before you fit a new synchronous belt, inspect the drive and sheaves so the replacement runs true and lasts.
Check the sheaves for worn grooves, burrs, corrosion or debris, and confirm they are aligned and secure. Verify that the belt path is clean and that any tensioner or idler turns freely. Correcting these points before installation helps prevent edge wear and premature belt failure.
Confirm the belt marking on the back of the old belt matches the profile, length and pitch you need. This Optibelt Alpha Flex belt is identified as 75 / 5M 6400 AFX, with an HTD 5M profile, 6400 mm length and 5 mm pitch. If the marking is worn or unreadable, measure the old belt and note the drive details.
For a quote, send the part number 75 / 5M 6400 AFX, the belt marking, and the drive or sheave information. Our team can confirm the right belt for your application and suggest an equivalent where one exists.
