This Optibelt Alpha Flex timing belt is identified by the code 25 AT10 / 12000 AFX. It is a synchronous belt with an AT10 profile, a 12000 mm length and a 10 mm pitch. Use it where a positive-drive timing belt of this profile and length is specified.
Timing belts in this class are common on drives that need synchronized motion rather than friction grip. The AT10 profile and 10 mm pitch define the tooth geometry and spacing that must match the pulley grooves. The 12000 mm length suits long-center-distance layouts where a single continuous belt spans the drive.
To confirm fit, read the marking on the back of the belt you are replacing and compare it with 25 AT10 / 12000 AFX. Check the profile and pitch against the pulleys, and verify the length matches the routing. If the marking is worn or unreadable, measure the belt and count teeth, then send the part number or those details for a quote.
