This Optibelt 75 AT5 / 3000 AFX timing belt is part of the Alpha Flex series. It has an AT5 profile, a 3000 mm length, and a 5 mm pitch. Use these three specifications to confirm it matches your drive before you request a quote.
The AT5 profile is a metric synchronous belt profile. The 5 mm pitch is the distance between tooth centers, and the 3000 mm length is the belt's datum length. These values must match the pulley and drive layout exactly for proper fit and timing.
When reading the marking on the back of your old belt, look for the profile, length, and pitch. The code 75 AT5 / 3000 AFX combines these key dimensions. If your current belt shows the same AT5 profile and 3000 mm length, this Optibelt belt is the correct replacement.
