This Optibelt Omega belt is a double-sided timing belt with a 640 mm length and a D5M profile. The D5M profile and 640 mm length are the two dimensions to confirm against your drive before ordering.
The D5M profile defines the tooth pitch and shape, while 640 mm is the belt's length. Both values are stated on this page exactly as they appear in the belt data. A double-sided timing belt has teeth on both faces, so it can drive pulleys from either side in reversing or multi-pulley layouts.
When matching an existing belt, read the marking on the back of the old belt and compare it with the code 640 D5M 9. If the marking is worn or unreadable, measure the length and identify the tooth profile from the pulleys. Send the part number and any photos of the old belt for a quote.
