This Optibelt Alpha Flex timing belt is identified by the code 50 AT10K13 / 10400 AFX. It uses the AT10 profile and has a length of 10400 mm, with a pitch of 10 mm. It is a synchronous belt for drives that require exact motion transfer.

AT10 profile timing belts are commonly found on large industrial drives where the belt runs over matching pulleys and must maintain synchronization. Typical uses include positioning systems, linear actuators, and other equipment where slip is not acceptable. The 10400 mm length and 10 mm pitch define the geometry, so the belt will only fit a drive built for that combination.

To confirm fit, check the old belt's back marking for the same code, profile, and length. The AT10 profile has a specific tooth shape, so it cannot be replaced by a different profile even if the length appears similar. If the marking is worn or missing, measure the length in millimeters and count the teeth to verify the pitch. The part number 50 AT10K13 / 10400 AFX should match exactly.

When requesting a quote, send the full code, the profile, and the length in millimeters. If you are unsure, a photo of the belt back and the drive pulleys helps our team confirm the correct item. We supply customers in the United States, Canada, Mexico, and South America, and we can suggest an equivalent when a direct match is not listed.
