The 280 2A pulley is a V-belt drive pulley, manufactured by EMMAR Accesorios Industriales. It has a 280 mm diameter and two grooves for section A belts. It is used to transmit power between parallel shafts in machines and industrial equipment, where a defined transmission ratio and good drive capacity are required. Its in-house manufacturing allows the machining to be adjusted to the assembly requirements, and being section A it accepts belts of that standard size.

This pulley has a 280 mm diameter, 2 grooves and section A. Section A corresponds to classic V-belts with a 13 mm top width, and the two grooves allow mounting two belts in parallel to distribute the load. The 280 mm diameter defines the transmission ratio when combined with another pulley in the same system. Being in-house manufacturing, EMMAR brand, the machining is done at the factory with dimensional control on the main measurements.

It is used in belt drives of machine tools, compressors, fans, centrifugal pumps, conveyor belts and process equipment. It is common in installations where revolutions need to be reduced or increased between an electric motor and the working shaft. It is also used in agricultural and industrial equipment that already has standardized section A belts and needs to replace the driving or driven pulley without modifying the rest of the system.

To select it, check that the belt is section A and that the number of grooves matches the number of belts you are going to mount. The 280 mm diameter must be compatible with the diameter of the opposite pulley to achieve the desired transmission ratio. Check the alignment between pulleys and the belt tension: misalignment accelerates flank wear and generates vibration. The keyway and the bore diameter are defined according to the shaft where it is mounted.

If you need a pulley with a different number of grooves, another diameter or a different section, it can be custom manufactured. To request an equivalent or a nearby size, send the code POLEA 280 2A or the MPN POLEA 280 2A by WhatsApp, along with the shaft diameter, the type of keyway and the belt section you use. With that data the part is confirmed and quoted.
