The Optibelt 5V KB 2120 is a banded V-belt from the KB SK series, built to keep multiple V-belts running as one unit on drives that cannot tolerate individual belt turnover or whip. It is used where several V-belts share a single set of pulleys and must stay matched in length and tension. Confirm fit by the profile and the 5385 mm length before ordering.

Banded V-belts are common on heavy-driven equipment such as large fans, blowers, compressors, crushers, and process machinery where a single V-belt would not carry the load. Because the belts are tied together across the top, the set stays aligned in the pulley grooves and resists flipping. The 5V KB 2120 is a 5V profile banded belt with a length of 5385 mm. If your drive uses a set of 5V belts and one has failed, replacing the full set is standard practice to keep lengths matched.

To confirm this belt fits your drive, read the marking on the back of the old belt and compare the profile and length. The part number should show 5V KB 2120, and the length should match 5385 mm. Also check the number of ribs in the band and the pulley grooves, since a banded belt must match both. If the marking is worn or unreadable, measure the outside length and the top width, and note the pulley diameters and center distance.
