The Optibelt 3V KB 1250 is a banded V-belt from the KB SK series with a length of 3175 mm. It is used where multiple V-belts run in parallel and must stay aligned. To match it to the belt being replaced, confirm the marking on the old belt and the drive setup.
Start by reading the back of the belt you are replacing. The part number 3V KB 1250, the series KB SK, and the 3175 mm length should match what is printed on the old belt. If the old belt is worn or the marking is unreadable, measure the outside length and check the profile against the pulley grooves.
A banded V-belt ties several V-belts together with a common backing. This keeps the belts from turning over or whipping on drives with pulsating loads or long center distances. When replacing, inspect all pulley grooves for wear and alignment, and check that the banded belt sits correctly in the grooves without bottoming out.
Send the part number 3V KB 1250, the series KB SK, and the length 3175 mm when you request a quote. If you have the old belt, include a photo of the back marking and the pulley arrangement. Our team can confirm the belt or suggest an equivalent based on the data you provide.
