The Optibelt 16 AT5 / 6800 AFX is an Alpha Flex timing belt with an AT5 profile, a 6800 mm length and a 5 mm pitch. Before you fit a new synchronous belt, inspect the drive and the sheaves, because worn or damaged components will shorten the life of any belt you install.

Start with the sheaves. Look for worn grooves, corrosion, chips, or buildup in the tooth spaces. Check that the sheaves run true and that the shafts and bearings have no play. Confirm the sheave teeth match the AT5 profile and that the belt sits correctly in the grooves. Misalignment between the two sheaves will cause the belt to track to one side and wear quickly, so check alignment with a straightedge or laser before tensioning.

Next, check the rest of the drive. Inspect the tensioner and idler pulleys for smooth rotation and worn surfaces. Clean the area so the new belt is not contaminated by debris or oil. When you install the Optibelt 16 AT5 / 6800 AFX, tension it according to the drive manufacturer's specification, rotate the drive by hand to seat the belt, then recheck tension and alignment.

If you are replacing a belt on a drive that uses more than one belt, replace all belts in the set at the same time. Mixed wear levels can cause uneven load sharing and premature failure. To request a quote, send the part number 16 AT5 / 6800 AFX, the quantity, and any details about the drive. If you need help confirming the right belt, include the old belt marking or photos of the drive and sheaves.
