The Optibelt 50 / 8M 4000 AFX is an Alpha Flex timing belt with an HTD 8M profile, a 4000 mm length and an 8 mm pitch. We carry this belt for maintenance, engineering and purchasing teams who need the exact part number confirmed before a drive is opened.

The fastest way to get a quote is to send the belt marking exactly as it appears on the back of the belt. For this item that is 50 / 8M 4000 AFX, together with the brand Optibelt and the series Alpha Flex. If the old belt is worn or the print is gone, send the profile and length from the drive documentation instead: HTD 8M and 4000 mm. A photo of the belt back and of the pulley grooves helps us confirm what you are running.

Include the quantity you need and whether the drive uses one belt or a matched set, since timing belts on the same drive are normally replaced together. If you are unsure whether this is the correct item, send the machine or drive reference along with the belt marking. Our team reviews the part number and the profile and length you provide, then replies by WhatsApp or email.

For requests covering several drives, list each belt on its own line with the full marking, the profile and the length in millimeters. That keeps the quote clear and makes it easy to check each line against the belt you are replacing.
