A Section Conventional V-Belt Cross References
Classic or conventional A-section V-belts are a type of mechanical drive belt with a trapezoidal cross-section designed to fit into the matching grooves of V-belt pulleys. These belts are widely used for power transmission in various industrial, agricultural, and automotive applications. Typically made from rubber or synthetic materials combined with reinforcement fibers for added strength, A-section V-belts are known for their durability, flexibility, and ability to handle a wide range of loads and speeds. They provide efficient power transmission through the wedging action between the belt and the pulley, which reduces slippage and increases the belt's grip. Their simple design and ease of maintenance make them a popular choice for reliable and cost-effective power transmission solutions.
