This Optibelt Alpha Flex timing belt is identified by the code 50 AT5K6 / 2000 AFX. The AT5 profile and 2000 mm length are the two dimensions to check first when matching a drive.
The AT5 profile is a synchronous belt profile. The 2000 mm length is the datum to compare against the old belt or the drive specification. The 5 mm pitch is the distance between tooth centers and must match the pulley groove spacing.
This is a timing belt, so it relies on tooth engagement rather than friction. Confirm the profile, length and pitch against the belt you are replacing before ordering. If the marking on the back of the old belt is worn, send a photo or the full code.
