The POLEA 300 7B pulley is a power transmission component manufactured by EMMAR Accesorios Industriales. It is a pulley with a 300 mm diameter, with 7 grooves for section B belts, used to transmit motion between shafts by means of V-belts. Its design allows several belts to be mounted in parallel, which makes it suitable for applications that require transmitting high power with a single assembly. It is a key part in industrial machines and equipment where reliability and durability are needed.

This pulley is identified with the designation POLEA 300 7B. Its main attributes are: 300 mm size, 7 grooves and section B. Section B corresponds to a standardized V-belt profile, and the 7 grooves allow the installation of the same number of belts. The 300 mm diameter defines the pitch diameter of the pulley, which together with the number of grooves determines the transmission capacity. It is an in-house manufactured part, EMMAR brand, produced under strict quality controls to ensure balanced and long-lasting operation.

Section B pulleys with multiple grooves are used in a wide variety of industrial applications. They are found in compressors, fans, pumps, mills, conveyor belts and machine tools, among other equipment. Their ability to transmit power through several belts makes them ideal for systems that require high torque and smooth running. They are also common in installations where a certain redundancy is needed, since the breakage of one belt does not completely stop the transmission.

To correctly select a pulley like this, it is essential to consider the power to be transmitted, the rotation speed and the diameter of the driven pulley. The transmission ratio is established between the pitch diameters of the driving and driven pulleys. In addition, it must be verified that the number of grooves is sufficient for the required power, according to the belts used. Mounting must be done on a shaft with the proper fit, and it is important to align the pulleys to avoid premature wear of the belts and bearings. MR Accesorios Industriales can advise on the selection of the assembly.
