The 310 2A pulley is a V-belt drive pulley manufactured by EMMAR Accesorios Industriales. It has a 310 mm diameter and two grooves for section A belts. It is used to transmit motion between parallel shafts in machines and industrial equipment, where a defined transmission ratio and good drive capacity are required. As it is in-house manufactured, variants of machining and balancing can be requested according to the application.

This item is a pulley with a 310 mm diameter, 2 grooves and section A. The designation POLEA 310 2A summarizes these three characteristics: the outer diameter of 310 mm, the number of grooves (2) and the belt profile it accepts (section A). It is a cast iron or steel pulley, depending on the manufacturing batch, and is machined to be mounted on a shaft with keyway. The number of grooves defines how many belts can work in parallel, which affects the transmitted power.

It is used in belt drives of machine tools, compressors, fans, pumps, conveyor belts and process equipment. It also appears in gear reducers and transmission systems where the speed between a motor and a driven machine needs to be adjusted. With two section A grooves, it is suitable for moderate powers and for applications where the load is distributed between two belts, with the advantage of continuing to operate if one of them fails.

To select it, take into account the pitch diameter, the number of grooves and the belt section, which must match the driving pulley and the available belt length. Check the shaft diameter and keyway before mounting. The alignment between pulleys and the correct belt tension are key to avoid premature wear. If the pulley operates at high revolutions, balancing should be evaluated. MR can manufacture variants with different diameters and grooves.

If you need an equivalent pulley or a nearby size, send us the part number POLEA 310 2A or the data of the original pulley: diameter, number of grooves, section and shaft diameter. With this data we can offer you an in-house manufactured alternative or a pulley from another series. We can also advise you if you need to replace an existing pulley and do not have the complete designation. The idea is that you can solve the transmission without stopping production.
