V-Belts, V Belts or Vee Belts, are commonly used in industrial applications to transmit power from a motor to a driven unit. The V-shaped geometry of V-Belts wedges the belt into the pulley groove for traction. Classical V-belts are the most common type of V-belt and are traditionally measured in imperial sizes. Narrow V-belts are ideal for high speed applications due to their greater depth to width ratio and are typically measured in metric sizings. V-Belts are used either individually or in sets, depending on the power requirements of the application.
