The Optibelt Alpha Flex 25 AT5 / 4200 AFX is a timing belt with an AT5 profile, a 4200 mm length and a 5 mm pitch. It suits synchronous drives where the belt's teeth mesh with matching pulleys to keep motion timed. Use this page to confirm the fit before you request a quote.

Timing belts like this one are common on drives that must stay in step: camshafts, conveyors, packaging equipment and other machines where slip is not acceptable. The AT5 profile and 5 mm pitch mean the belt runs on pulleys cut to the same profile and pitch. Check that your pulleys match before ordering.

To confirm fit, read the marking on the back of the old belt and compare it with the part number above. The two figures that matter most are the profile, AT5, and the length, 4200 mm. If the old belt is worn or the marking is gone, measure the length along the pitch line and count the teeth if you can.

We carry the Optibelt Alpha Flex line and quote by part number. Send the belt code, the profile and the length, and a photo of the back marking if you have one. Our team can confirm the belt or suggest an equivalent.
