This Optibelt Alpha Flex timing belt is identified by the code 100 AT20 / 8600 AFX. It uses the AT20 profile with a 20 mm pitch and an 8600 mm length. It is a synchronous belt for drives that require exact timing between shafts.
Timing belts like this are used on industrial drives where the belt teeth mesh with pulley grooves to keep the driven shaft synchronized with the drive shaft. The AT20 profile is a metric tooth form, and the 20 mm pitch and 8600 mm length define the belt's fit on the pulleys and the center distance of the drive. This belt is not for standard V-belt pulleys or serpentine setups; it requires matching AT20 profile sprockets.
To confirm fit, read the marking on the back of the old belt and compare the profile, pitch and length to this page. Check the pulley grooves for wear and make sure the belt width matches the pulley face. If the old belt is worn or damaged, inspect the drive for misalignment or damaged teeth before ordering a replacement.
