When you read the marking on an old banded V-belt, the part number is the key to a correct replacement. This page covers the Optibelt 3-B 4000, a banded V-belt with a 4000 mm length. Use the marking to confirm the part number before requesting a quote.
The Optibelt 3-B 4000 is identified by its part number and 4000 mm length. If the original belt is worn or damaged, check the back of the belt for the marking. The part number and length are the details needed to match the belt. Because this is a banded V-belt, it consists of multiple V-belts joined by a top band, which keeps them aligned and reduces vibration in drives that use several belts side by side.
