A / SPA Section Pulleys

A V Pulley — also known as a V‑belt pulley — is a grooved wheel designed to transmit power between rotating shafts using a V‑shaped belt. The groove’s angled profile matches the belt’s trapezoidal cross‑section, allowing the belt to wedge firmly in place for high‑friction, slip‑resistant power transfer. V Pulleys are manufactured to suit different belt section sizes — such as A, SPA, Z, and SPZ — each with specific widths and depths to match the pulley groove. These belts, often called wedge belts or V belts, enable efficient torque transmission across a wide range of industrial, automotive, and agricultural applications, with the pulley and belt profile carefully matched to ensure maximum performance and service life
