This Optibelt Alpha Flex timing belt is identified by the code 25 AT10K13 / 3400 AFX. It uses an AT10 profile with a 10 mm pitch and a 3400 mm length. The AT10 profile is common in industrial drives where positive, synchronous power transmission is required.
To confirm fit, compare the marking on the back of the old belt with the code 25 AT10K13 / 3400 AFX. Check that the profile is AT10, the pitch is 10 mm, and the length is 3400 mm. Because the belt is a synchronous type, the tooth profile and pitch must match the pulleys exactly.
The AT10 profile is used in a range of industrial timing drives, from production machinery to conveying systems. If you are replacing a worn belt, inspect the pulleys for tooth wear, alignment, and tension before installing the new belt. A belt that is the correct length but the wrong profile will not run correctly.
For a quote, send the part number 25 AT10K13 / 3400 AFX, the quantity you need, and any details from the old belt. Our team can confirm the belt or suggest an equivalent based on the profile and length. We supply customers in the United States, Canada, Mexico, and South America.
