The Optibelt D 120 KB is a banded V-belt built for drives that use multiple V-belts running in parallel. Banding ties the belts together so they act as one unit, which helps keep them from turning over or whipping on the drive. This page covers where the D 120 KB fits and what to check before you order.
Banded V-belts like the D 120 KB are common on heavy-duty drives where two or more V-belts run side by side on the same sheaves. Because the belts are joined across the top, the set stays aligned through the pulleys and resists the flip and flutter that single belts can develop under shock loads. If your drive was built for a banded set, replacing it with loose belts usually leads to uneven wear and a short service life.
To confirm the D 120 KB is the right belt, read the marking on the back of the old belt and compare it to the part number. Check that the belt is a banded V-belt and that the number of ribs in the band matches the number of grooves on your sheaves. Inspect the sheaves for wear, chips or buildup in the grooves, and make sure the drive is aligned before you install a new set.
If the marking is worn off or you are unsure of the number, send a photo of the old belt and the drive to our team by WhatsApp or email. We carry the Optibelt D 120 KB and can confirm the part number or help you find the belt that matches your drive.
