This Optibelt Alpha Flex timing belt is identified by the code 50 AT5K6 / 9000 AFX. It uses an AT5 profile with a 5 mm pitch and a 9000 mm length. It is a synchronous belt intended for industrial drives that require precise motion and timing.
Timing belts like this Optibelt unit are used in industrial machinery where the driven components must stay synchronized with the drive. Common examples include positioning systems, indexing drives, and other equipment that depends on exact speed ratios rather than friction. The AT5 profile and 5 mm pitch define the tooth geometry that must match the pulleys.
To confirm fit, compare the belt marking on the back of the old belt with the code 50 AT5K6 / 9000 AFX. Check that the profile is AT5, the pitch is 5 mm, and the length is 9000 mm. The pulley grooves must also be compatible with the AT5 profile. If the marking is worn or unreadable, measure the belt length and count the teeth to verify the pitch before ordering.
When you request a quote, send the full belt code, the profile, the length, and the pitch. If you have the old belt, include a photo of the back marking and the pulley. Our team can help confirm the correct belt or suggest an equivalent based on the data you provide.
