This Optibelt Alpha Flex timing belt is identified by the code 25 AT20 / 5800 AFX. It uses the AT20 profile with a 20 mm pitch and a 5800 mm length. It is a synchronous belt intended for drives that require exact timing between shafts.
Timing belts like this are commonly found on industrial drives where shaft synchronization is critical, such as camshafts, conveyors, and positioning systems. The AT20 profile and 20 mm pitch define the tooth shape and spacing that must match the pulleys. The 5800 mm length is the datum length for this belt.
To confirm fit, check the marking on the back of the old belt and compare the profile, pitch, and length. The code 25 AT20 / 5800 AFX contains the key dimensions. If the marking is worn, measure the pitch and count the teeth, then verify the pulley profile. Send the part number and any photos of the old belt for a quote.
