This page covers the Optibelt 32 AT20 / 3800 AFX timing belt from the Alpha Flex series. If you are replacing a belt on a driven unit, the first step is to match the profile and the length to what is on the drive now. The marking on the back of the old belt is the fastest way to confirm both.
A timing belt is selected by profile and length before anything else. This belt is profile AT20, with a length of 3800 mm and a pitch of 20 mm. Read those values off the old belt and compare them to the data here. If the profile and length agree, you are looking at the same size.
On a worn belt the print can be faint, so check the drive as well. Count the teeth if the marking is unreadable, and note the width of the belt and the width of the pulleys. A belt that has run hot or walked to one side often points to a pulley or tension issue rather than the belt itself, and that is worth catching before the replacement goes on.
We carry the Optibelt 32 AT20 / 3800 AFX for maintenance, engineering and purchasing teams. To request a quote, send the part number, the quantity and the width you need by WhatsApp or email. If you are unsure the profile is right, send a photo of the back of the old belt with the marking visible and we can help confirm it.
