This is an Optibelt Alpha Flex timing belt, part number 50 AT5 / 11400 AFX. It is a synchronous belt with an AT5 profile, a 5 mm pitch and a 11400 mm length. Long synchronous belts of this type are commonly used on wide, low-speed drives where the belt runs across a long center distance.
Because the belt is long, confirming fit starts with the drive itself rather than the old part number alone. Check the pulley grooves against the AT5 profile and the 5 mm pitch, then measure the belt path around the pulleys and any idlers to verify the 11400 mm length. On a long drive, a small error in routing or in the number of idlers adds up over the full loop.
Read the marking on the back of the old belt and compare it with 50 AT5 / 11400 AFX. If the marking is worn or unreadable, count the teeth and confirm the pitch and profile from the pulleys. Send the part number, the profile and length, and the drive details to MR by WhatsApp or email and the team will confirm the belt or suggest an equivalent.
