This Optibelt Alpha Flex timing belt is identified by the code 50 AT5K6 / 11800 AFX. It has an AT5 profile, a 5 mm pitch and an 11800 mm length, and we carry it for linear motion and power transmission drives that use synchronous belts.
Timing belts in this size range are commonly found on large-format gantry systems, indexing conveyors and other drives where the belt runs over matching AT5 pulleys. The AT5 profile and 5 mm pitch determine how the belt seats in the pulley grooves, so confirm that your drive uses AT5 pulleys before ordering.
To match an existing belt, read the marking on the back of the belt and compare it with 50 AT5K6 / 11800 AFX. Check the profile and the length in millimeters against your drive documentation or a measured belt. If the old belt is worn or the marking is unreadable, send the drive details and any pulley information for confirmation.
When you request a quote, include the part number 50 AT5K6 / 11800 AFX and the quantity you need. If you are replacing more than one belt on the same drive, list each belt so we can help you confirm the correct items.
