The Optibelt 50 / 8M 4400 AFX is an Alpha Flex timing belt with an HTD 8M profile, an 8 mm pitch, and a 4400 mm length. It is the kind of synchronous belt used on industrial drives where the pulley grooves and the belt teeth must mesh exactly to keep the driven shaft in step with the motor. Confirm fit by reading the marking on the back of the belt and matching the profile and length before you order.

HTD 8M synchronous belts like this one are common on drives that need positive power transmission rather than friction, such as cam drives, indexing equipment, and other machinery where slip is not acceptable. The 8 mm pitch and 4400 mm length define the belt, so both values need to match the drive you are working on. Check the tooth profile against the pulley grooves as well, since an HTD 8M belt will only seat correctly on an HTD 8M pulley.

The most reliable way to identify a replacement is to read the marking on the back of the old belt. If the printing is worn, measure the length and confirm the profile from the pulley, then send that information with the part number. A belt that is close in length but wrong in profile will not run correctly, and the drive will show it quickly.

When you request a quote, send the part number 50 / 8M 4400 AFX, the quantity, and any details you have from the drive. The team at MR can confirm the belt or suggest an equivalent from what we carry. If you are replacing more than one belt on the same drive, order them together so the set is matched.
