This Optibelt Alpha Flex timing belt carries the part number 25 AT10K13 / 6400 AFX. The marking identifies an AT10 profile and a 6400 mm length, so you can confirm the drive fit before ordering.
The AT10 profile is a synchronous belt tooth form with a 10 mm pitch. The 6400 mm length is the datum for matching the belt to your drive layout. Together, profile and length are the two numbers to check first when reading the back of an old belt or a machine manual.
This is a timing belt, also called a synchronous belt. It is built for drives where the belt teeth mesh with pulley grooves to keep the driven shaft timed to the driver. If your current belt shows this part number, this is the same size to request.
