This Optibelt Alpha Flex timing belt is identified by the code 25 AT5K6 / 12000 AFX. The AT5 profile and 12000 mm length define the belt's fit, so both values should be checked against the drive before ordering.
The profile is AT5, a synchronous belt profile with a 5 mm pitch. The overall length is 12000 mm. These two figures, profile and length, are the primary selection criteria when matching a replacement to an existing drive.
To confirm the correct belt, read the marking on the back of the belt you are replacing and compare it with the code above. If the marking is worn or unreadable, measure the length and identify the profile from the pulley grooves.
We carry the Optibelt Alpha Flex line and supply this belt to maintenance, engineering and purchasing teams across the United States, Canada, Mexico and South America. Send the part number by WhatsApp or email and our team will confirm the belt or suggest an equivalent.
