If the marking is worn or unreadable, measure the length and count the teeth, then send those details with your request.
A timing belt is selected by profile and length, not by the machine alone. The HTD 8M profile and the 4400 mm length must match the pulleys and the drive layout. If the old marking shows a different profile or length, do not force this belt onto the drive. Send the marking or the measurements, and we will help confirm the right belt or suggest an equivalent.
When you request a quote, include the part number 100 / 8M 4400 AFX and the quantity. If you have the old belt, a photo of the back marking helps. For drives that run more than one belt, replace the set together and inspect the pulleys for wear before installation.
