This Optibelt Alpha Flex timing belt carries the part number 75 AT5 / 4000 AFX. It uses an AT5 profile with a 5 mm pitch and a 4000 mm length. Use the part number and these dimensions to confirm the belt matches your drive before you request a quote.
Timing belts in this AT5 profile and 4000 mm length are used on synchronous drives where the belt teeth mesh with matching pulleys to keep the driven shaft in step with the drive. Typical settings include production and packaging machinery, conveyors, and other equipment with long center distances. The AT5 profile and 4000 mm length are the two figures to check first against the belt you are replacing.
To confirm fit, read the marking on the back of the old belt and compare it with 75 AT5 / 4000 AFX. Check the profile as AT5 and the length as 4000 mm, and confirm the belt width matches the pulleys. If the marking is worn or the belt is missing, send the machine make and model, the pulley dimensions, and photos of the drive and the old belt. Our team can help confirm the correct belt or suggest an equivalent.
