The 80 3A pulley is a V-belt drive pulley, manufactured by EMMAR Accesorios Industriales. It has an 80 mm diameter, 3 grooves and section A. It is used to transmit motion between parallel shafts in industrial machines and equipment, where a defined transmission ratio is needed and the possibility of adjusting it by changing groove or diameter. Its in-house construction allows adapting the machining to the size and type of keyway required by each application.

This item is a pulley with an 80 mm diameter, 3 grooves and section A. The designation POLEA 80 3A summarizes those three variables: the outer diameter, the number of grooves and the belt profile it accepts. Section A corresponds to classic V-belts with a narrow profile, suitable for moderate power and medium speeds. As it is in-house manufacturing, EMMAR brand, the machining of the bore, the keyway and the balancing are adjusted according to the shaft and working conditions indicated by the customer.

Typical applications of a 3-groove section A pulley appear in drives of machine tools, compressors, fans, centrifugal pumps, light conveyor belts and factory equipment. When several speed ratios or greater drive capacity are needed, the 3 grooves allow distributing the load among several belts and reducing the risk of slipping. It is also used to replace worn pulleys or to build a new drive from scratch.

To select and mount this pulley, verify that the 80 mm diameter is compatible with the desired transmission ratio and that the 3 section A grooves match the available belts. The bore must be machined to the exact shaft diameter, with tolerance and keyway according to standard. It is important to align the pulleys with each other and tension the belts evenly to avoid uneven wear. If the pulley runs at high revolutions, it is advisable to check the balancing before putting it into service.
