The Optibelt 150 / H 3940 AFX is a timing belt from the Alpha Flex series, built with an H profile and a 10007.6 mm length. We carry it for maintenance, engineering and purchasing teams who need to replace a synchronous belt on a specific drive. Confirm the fit before you order.

Synchronous belts of this type are common on drives where the belt teeth mesh with matching pulleys to keep the driven shaft timed to the drive shaft. If your equipment runs an H profile belt at this length, this part number is the one to check against the drive. Review the belt you are removing, the pulley grooves and the routing before you commit.

The most reliable way to confirm fit is to read the marking on the back of the old belt. Compare the profile and the length on that marking with the H profile and 10007.6 mm length listed here. Check that the belt width suits the pulleys and that the drive has no damaged or worn teeth that would affect a new belt.

For a quote, send the part number 150 / H 3940 AFX, the quantity and any details from the old belt marking. If you are unsure whether this is the right belt, send a photo of the marking and the drive. Our team can help confirm the right belt or suggest an equivalent.
