This Optibelt Alpha Flex timing belt is identified by the code 50 AT20 / 5200 AFX. It uses the AT20 profile with a 20 mm pitch and a 5200 mm length. This type of synchronous belt is used where teeth mesh with pulleys to keep a drive synchronized, such as on larger industrial equipment and processing lines.
To confirm fit, check the marking on the back of the old belt against the code 50 AT20 / 5200 AFX. The AT20 profile and 20 mm pitch must match the pulley grooves, and the 5200 mm length must match the drive layout. If the old belt is worn or the marking is unreadable, measure the profile and pitch at the pulley and confirm the length along the belt path.
Because this is a long, wide synchronous belt, it is often part of a drive where both pulleys and the belt are replaced together. Inspect the pulleys for worn teeth, debris in the grooves and correct alignment before installing a new belt. Send the belt code, the profile and the length when you request a quote, and the team can help confirm the right belt or suggest an equivalent.
