This TB Woods bored-to-size V-belt sheave with a B belt section is made of cast iron and comes with one groove. It is a classical V-belt sheave that fits a variety of widely available, classical profile V-belts suitable for use in many existing power transmission drives. This pulley is made of cast iron for resistance to wear, corrosion, and galling. It has a B cross section and 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. 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.

TB Wood's manufactures sheaves, V-belts, couplings, bushings, and other power transmission products. Founded in 1857, it is based in Chambersburg, PA.
