This Optibelt Alpha Flex belt is a timing belt in the HTD 8M profile with a length of 3800 mm and a pitch of 8 mm. It is identified by the part number 85 / 8M 3800 AFX. Synchronous belts of this type are used where a drive must keep the driven shaft in step with the driver, so confirming the profile and length against the application is the first step.

Timing belts in the HTD 8M profile are common on industrial drives that need positive engagement rather than friction, including machinery where shaft synchronization matters. The 8 mm pitch and 3800 mm length define the fit on the pulleys, so both values should be checked against the drive before ordering. The belt carries the marking 85 / 8M 3800 AFX on the back.

The most reliable way to confirm a replacement is to read the marking on the old belt and compare it with the profile and length above. If the old belt is worn or the marking is no longer legible, measure the drive and note the pulley tooth profile and the belt length. Send the part number 85 / 8M 3800 AFX by WhatsApp or email and our team will confirm the belt or suggest an equivalent.

When a drive runs more than one belt, replace the set together so the load stays evenly shared. Inspect the pulleys at the same time for worn teeth, alignment and tension, since these affect belt life.
