The Optibelt 150 / H 3700 AFX is an Alpha Flex timing belt with an H profile and a 9398 mm length. When you need to match a belt on an existing drive, start with the marking on the back of the old belt.

The marking typically shows the profile and the length, so an H profile and 9398 mm points directly to this Optibelt belt. Copy the full code, including the AFX suffix, and send it to us by WhatsApp or email. We carry Optibelt and will confirm the belt or suggest an equivalent from the same profile and length.

If the back of the belt is worn or the print is gone, measure the length and check the pulley groove profile. The H profile and 9398 mm length are the key dimensions. A timing belt that matches both will sit correctly in the grooves and maintain the drive's timing relationship.

For a quote, send the part number 150 / H 3700 AFX or the profile and length. If you are replacing more than one belt on the same drive, include all the markings so we can help you keep the set consistent.
