The Optibelt 100 / H 3780 AFX is a timing belt in the Alpha Flex series. It uses an H profile and measures 9601.2 mm in length. This page covers what those two figures tell you before you match the belt to your drive.
The profile sets the tooth geometry that engages the pulley. An H profile belt runs on H-profile pulleys, so the first check is that the sprockets on your drive carry the same designation. The 9601.2 mm length is the second fixed point. Measure the old belt or read the marking on its back, then compare both figures against this listing. If either one differs, the belt will not seat or track correctly.
For a quote, send the part number 100 / H 3780 AFX, the profile H, and the length 9601.2 mm. If you are replacing a belt that is worn or unreadable, include the drive details and a photo of the old belt. Our team can confirm the belt or suggest an equivalent.
Timing belts should be inspected for tooth wear, cracking, and cord exposure. On a drive that uses more than one belt, replace the set together so the load stays even. Confirm pulley alignment and tension before the drive goes back into service.
