This Optibelt Omega belt is a double-sided timing belt with a 4578 mm length. It is used where a drive needs synchronous teeth on both faces, such as reversing or multi-pulley layouts. Confirm fit by matching the part number and the 4578 mm length to the belt you are replacing.

Double-sided timing belts are common on drives where one belt turns two or more pulleys in opposite directions, or where the back of the belt also drives an accessory. Before ordering, read the marking on the back of the old belt and compare it with 4578 D14M SL 285. Check that the belt path has the same number of pulleys and that the teeth engage on both sides as the original did.

Length is the first check. This belt is listed at 4578 mm. If the old belt is worn or stretched, measure the drive or use the original marking rather than a tape measure alone. Also confirm the belt is a double-sided timing belt, not a single-sided timing belt or a V-belt, since the profile and tooth pattern must match the pulleys.

For a quote, send the part number 4578 D14M SL 285 and the quantity you need. If you are replacing more than one belt on the same drive, include all the markings so we can help you confirm the right belt or suggest an equivalent. Photos of the belt back and the drive layout can help us verify the match.
