Classic A section V-belts are exactly that, classic in design and application. The classic A v-belt is the most tried and true style of v-belt in the market. Originally designed to replace leather belts in a variety of industries including agriculture, facility maintenance, heating ventilation and air conditioning (HVAC), and lawn & garden. Also known as a light-duty v-belt, they are designed with a 40° angle to "wedge" the belt into the groove of the pulley. The greater the load, the greater the wedging action. The manufacturing process combines a rubber compound with a polyester cord to increase strength and stability. Most A belts are also available in Kevlar.
A section V-belts are conventional wrapped v-belts suitable for all standard industrial applications. Standard operating temperatures ranging from -1° F through 158° F.
