V-belts A137 are commonly used in industrial applications because of their relative low cost, ease of installation. The A137 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 A137 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.
