This Optibelt Alpha Flex belt is a timing belt with an AT5 profile, a 12000 mm length and a 5 mm pitch. It is used where a synchronous drive must carry motion at a fixed ratio over a long center distance.
Long-length timing belts in this profile are common on wide-format printing equipment, textile and packaging machinery, and other line-shaft or traverse drives where the belt runs between distant pulleys. The AT5 profile and 5 mm pitch suit small-to-medium pitch pulleys, so confirm the pulley groove form and tooth count match the belt before ordering.
To confirm fit, read the marking on the back of the old belt and compare it with the profile, length and pitch shown here. Check that the drive uses AT5 pulleys and that the 12000 mm length matches the measured belt or the machine's specified length. Send the part number 25 AT5 / 12000 AFX, the belt marking, and the pulley tooth count for a quote.
Inspect the drive for worn pulley teeth, misalignment and correct tension before fitting a new belt. Where a machine uses more than one belt on the same drive, replace them as a set so the load stays even.
