The Optibelt 5-C 3700 is a banded V-belt from the KB VB series, built for drives that use multiple C-section grooves. It keeps several V-belts tied together so they run as one unit on the same pulley set. This page covers where this type is used and how to confirm it fits your drive.

Banded V-belts are common on heavy industrial drives where a single belt would slip or whip under load. Because the ribs are joined across the top, the belt stays aligned in the grooves and resists the turning and flipping that can affect individual belts on long center distances. The 5-C 3700 is a C-section banded belt with a length of 3700 mm.

To confirm fit, read the marking on the back of the belt you are replacing and match the part number, the section and the length. Check the pulley grooves for wear and make sure the number of ribs on the new belt matches the number of grooves in the drive. If the old belt is worn or stretched, replace the full set rather than mixing new and used belts on the same drive.

If the marking is worn off, send a photo of the belt and the drive, the pulley diameters and the number of grooves. Our team can help confirm the right belt or suggest an equivalent.
