This Optibelt Alpha Flex timing belt is identified by the code 150 / H 3860 AFX. It has an H profile and a length of 9804.4 mm. It is a synchronous belt intended for drives that require exact timing between the pulley teeth and the belt teeth.

Timing belts of this type are used on industrial drives where shaft synchronization matters, such as camshafts, conveyors, and other positive-drive applications. The H profile and 9804.4 mm length define the fit on the pulleys. Confirm that your drive uses an H-profile pulley and that the belt path measures 9804.4 mm before ordering.

The easiest way to match a replacement is to read the marking on the back of the old belt. If the code reads 150 / H 3860 AFX, this is the same belt. For a quote, send that full code, the profile H, and the length 9804.4 mm by WhatsApp or email. The team replies promptly and can help confirm the right belt or suggest an equivalent.

Inspect the drive before replacement: check pulley teeth for wear, verify alignment, and confirm the belt is correctly tensioned. Replacing a timing belt is best done as part of a planned maintenance step, with the drive locked out and the old belt kept for comparison.
