The Optibelt 20 / 8M 3000 AFX is an Alpha Flex timing belt in the HTD 8M profile. It measures 3000 mm in length on an 8 mm pitch. To match it to the belt you are replacing, read the marking on the back of the old belt and compare it against these figures before you order.

Start with the profile and the length. The replacement has to run the same tooth form and the same length as the belt coming off the drive, so confirm HTD 8M and 3000 mm against the old marking rather than against a measurement taken on the machine. The 8 mm pitch is part of the profile and should line up with what is printed on the belt.

The part number itself is the quickest check. If the back of the old belt reads 20 / 8M 3000 AFX, this is the same item. If it reads something else, send us the full marking and the width, and we will confirm what you need or suggest an equivalent that fits the drive.

A timing belt usually comes off because something else moved. Before the new belt goes on, check the pulleys for worn teeth, the flanges for rubbing, and the tensioner for free travel. On drives that run more than one belt, replace them as a set so the load stays even across the group.
