The Optibelt 30 / 8M 7800 AFX is an HTD 8M timing belt from the Alpha Flex series. It has a 7800 mm length and an 8 mm pitch, and we carry it for long-span synchronous drives where positive tooth engagement is required.
Timing belts of this profile are used on drives where the belt must maintain a fixed relationship between the pulleys, such as camshaft or auxiliary drives on larger engines and industrial equipment. The HTD 8M tooth profile is a common choice for these applications, and the 7800 mm length suits long center distances.
To confirm fit, check the belt marking on the back of the old belt. The part number should read 30 / 8M 7800 AFX. The profile is HTD 8M, the pitch is 8 mm, and the length is 7800 mm. If the marking matches, the belt is the correct size.
If you need to confirm the right belt or an equivalent, send a photo of the old belt marking, the pulley tooth count, and the center distance to our team by WhatsApp or email. We will help verify the profile and length before you order.
