V-belt pulleys (sheaves) are the component in a power transmission drive that transmits power to the belt. Typically made of cast iron, the pulleys and the V-belts that loop around them match in form – wide (classical) or narrow, single or multi-grooved. V-belt pulleys are found in drive designs in the agriculture, textile, printing, mining, and office equipment industries.
