This Optibelt Alpha Flex timing belt is identified by the code 50 AT20 / 6600 AFX. It uses the AT20 profile with a 20 mm pitch and a 6600 mm length. It is a synchronous belt intended for drives where tooth engagement and length are specified by the equipment builder.

Timing belts in this size range are commonly used on large industrial drives where the belt runs over matched pulleys and must maintain a fixed relationship between shaft positions. The AT20 profile and 6600 mm length are the key dimensions to confirm before ordering. Check the marking on the back of the existing belt and compare it with the code above.

To confirm fit, verify the profile is AT20, the pitch is 20 mm and the length is 6600 mm. Also check the belt width against the pulley groove width, because the code 50 AT20 / 6600 AFX identifies the belt but the width must match the drive. If the old belt is worn or the marking is unreadable, measure the length and count the teeth to confirm the replacement.
