V-belts are characterized by their trapezoidal cross-section, which allows them to fit snugly into the grooves of pulleys. This unique design enables them to handle high loads while remaining efficient in their operation. They are widely used to transfer power from an engine or motor to various components, such as pumps, fans, and alternators. The design and manufacturing of v-belts have evolved over the years, with advancements in materials and engineering leading to improved durability, flexibility, and performance.
