The B21 has a V-shape that makes it easier to keep the belt in sheave grooves on fast moving applications. The biggest operational advantage of the B21 V-belt is the wedging action into the sheave groove. This geometry multiplies the low tensioning force to increase friction on the pulley sidewalls improving the power transmission.
