The Optibelt 25 / 5M 2100 AFX is an Alpha Flex timing belt with an HTD 5M profile, a 2100 mm length and a 5 mm pitch. Before you fit it, inspect the drive so the new belt is not damaged by worn components. We carry this belt and quote it by part number.

Start with the sheaves. Check the tooth flanks for wear, the grooves for embedded debris and the bore and keyway for movement. A sheave that has worn out of shape will wear a new belt quickly, so measure it and replace anything out of tolerance before the belt goes on.

Check alignment and tension next. Confirm the shafts are parallel and the sheaves are in line, since misalignment pulls the belt to one side and shortens its life. Look at the bearings and the structure for looseness, and set tension to the drive manufacturer's specification rather than by feel.

Then check the old belt itself. Compare the profile and length on its back with the HTD 5M profile and 2100 mm length of this Optibelt Alpha Flex belt, and confirm the width matches the sheave. If the marking is worn off, send us the drive details and we can help confirm the correct belt.
