The 50 2B pulley is a power transmission pulley of in-house manufacturing, EMMAR Accesorios Industriales brand, with a 50 mm diameter, two grooves and section B. It is used to transmit motion between shafts through V-belts, in equipment where a fixed transmission ratio and a compact mounting are required. Its two-groove construction allows it to handle more power than a single pulley of the same diameter, maintaining belt alignment and tension.

This item is a pulley with a 50 mm diameter, with 2 grooves and section B. The designation POLEA 50 2B summarizes those three characteristics: the 50 mm outer diameter, the number of grooves (2) and the belt profile it accepts (section B). It is an in-house manufactured part, EMMAR brand, designed to be mounted on shafts and transmit torque through V-belts. Section B is one of the most widely used in medium-power industrial transmissions.

Typical applications include machine tools, compressors, fans, centrifugal pumps, conveyor belts and factory equipment. In all cases, the pulley is selected by diameter, number of grooves and belt section, which must match the rest of the system. It is also used to replace worn pulleys or when the transmission ratio is modified by changing the diameter of one of the pulleys in the assembly.

To correctly mount and select it, verify that the shaft diameter matches the pulley bore (which is defined at the time of purchase) and that the belt section is B. The grooves must be aligned with those of the driving pulley to avoid premature wear. Belt tension is adjusted according to the equipment manual. If the pulley operates at high revolutions, it is advisable to check the balance and the condition of the grooves before installing it.
