This Optibelt Alpha Flex timing belt is identified by the code 75 AT20 / 4200 AFX. It has an AT20 profile and a 4200 mm length, with a 20 mm pitch. It is used in drives that require synchronous power transmission and precise positioning.
To confirm fit, check the belt marking on the back of the old belt. The profile, length, and pitch must match the drive's pulleys and the original specification. If the marking is worn or missing, measure the old belt and compare it with the AT20 profile and 4200 mm length listed here.
Timing belts are common in industrial machinery where shaft synchronization is critical, such as packaging equipment, printing presses, and CNC machines. The AT20 profile is a metric pitch profile, and the 20 mm pitch indicates the distance between tooth centers. This belt is not a V-belt or a serpentine belt, so it should not be used in drives designed for those types.
When requesting a quote, provide the full part number 75 AT20 / 4200 AFX and the quantity needed. If you are replacing multiple belts on the same drive, include all part numbers so we can help you confirm the correct items. For assistance identifying the right belt, send a photo of the old belt's marking and the drive setup.
