The Optibelt 400 / H 1025 AFX is an Alpha Flex timing belt with an H profile and a length of 2603.5 mm. When you are replacing a belt, the most reliable match is the one printed on the old belt itself.
Remove the old belt and read the marking on the back. The part number 400 / H 1025 AFX, the profile H and the length 2603.5 mm are what you need to compare. If the marking is worn, measure the length and count the teeth to confirm the profile. A belt with the same profile and length will fit the same pulleys and maintain the drive's timing.
We carry the Optibelt 400 / H 1025 AFX Alpha Flex timing belt. To request a quote, send the part number 400 / H 1025 AFX by WhatsApp or email. If you are unsure, include photos of the old belt and any markings. Our team can confirm the right belt or suggest an equivalent.
Inspect the drive before installing a new belt. Check the pulleys for wear, alignment and tension. Replace the belt if you see cracks, missing teeth or exposed cords. For drives with multiple belts, replace them as a set to keep loads even.
