This Lovejoy grooved V-belt driven (companion) sheave for variable speed drives is made of cast iron and works with widely available, variable speed belts suitable for use in many existing drive designs. This sheave is made of cast iron for resistance to wear, corrosion and galling and is designed for variable speed applications. Its spoked construction provides strength while decreasing weight, and it has one groove for use with single belts. V-belt pulleys (sheaves) are used in a wide range of mechanical and electronic drives, including HVAC units, farm machinery, food processing equipment, and home appliances, among others.

V-belt pulleys (sheaves) are the component in a power transmission drive that transmits power to the belt.
