The Optibelt 300 / H 435 AFX is an Alpha Flex timing belt with an H profile and a length of 1104.9 mm. This page gives you the profile and length data you need to confirm it against your drive.
Profile and length are the two dimensions that decide whether a timing belt fits. The H profile sets the tooth shape and pitch; the 1104.9 mm length sets the belt's path around the pulleys. Both are stated for this Optibelt Alpha Flex belt, so you can compare them directly with the belt you are replacing or with the drive's specification.
If you are matching an existing belt, read the marking on the back of the belt and check it against the part number 300 / H 435 AFX. When the marking is worn or unreadable, measure the old belt and confirm the profile and length before ordering.
