This Optibelt Alpha Flex timing belt carries the code 100 AT20 / 3000 AFX. It is a synchronous belt with an AT20 profile, a 3000 mm length, and a 20 mm pitch. Use these three values to match it against the belt you are replacing.
Start with the marking on the back of the old belt. If it reads 100 AT20 / 3000 AFX, this is the same belt. If the profile is AT20 and the length is 3000 mm with a 20 mm pitch, the size matches even when the printed code differs. Confirm the profile and length before ordering.
When the old marking is worn or unreadable, measure the belt and check the drive. The profile must match the pulley grooves and the length must suit the drive layout. Send the part number, profile, and length with your request for a quote, and we will confirm the belt or suggest an equivalent.
