The POLEA 120 2B pulley is a V-belt drive pulley, in-house manufactured, EMMAR brand, with a 120 mm diameter, 2 grooves and section B. It is used to transmit power between parallel shafts in industrial equipment, with the advantage that, being domestically produced, it can be adapted to the needs of each machine. It is a key part in the maintenance of production lines, mills, conveyor belts and ventilation systems.

This item is a pulley with a 120 mm diameter, 2 grooves and section B. The POLEA 120 2B designation summarizes those three variables: the outside diameter, the number of grooves and the belt profile it accepts. Section B corresponds to a type of V-belt widely used in medium-power drives. Being in-house manufactured, EMMAR brand, the machining and balancing are controlled so that the pulley rotates without vibrations and with correct alignment.

The typical applications of a 2-groove section B pulley are equipment that requires transmitting torque with a certain redundancy: if one belt fails, the other keeps pulling. It is found in industrial fans, compressors, centrifugal pumps, mills, mixers and conveyors. Also in agricultural machinery and factory equipment. Due to its 120 mm diameter, it is suitable for drive ratios where a moderate output speed is sought.

To mount this pulley, verify that the shaft has a compatible diameter and keyway, and that the tapered or cylindrical bore matches the fastening system. Check the alignment between pulleys with a straightedge or laser: a misalignment of a few degrees shortens belt life. Tension must be the one recommended by the belt manufacturer; too little tension slips, too much strains the shaft bearings. If the pulley runs at high revolutions, it should be balanced.

If you need an equivalent pulley or a nearby size, the most practical thing is to send us the POLEA 120 2B part number or the data of the original pulley: diameter, number of grooves, section and bore diameter. With that data we can offer you an in-house manufactured pulley with the same performance or a variant with another diameter. We can also manufacture to measure if the volume justifies it. Ask us by WhatsApp and we will reply with the available alternative.

At MR Accesorios Industriales we have been manufacturing pulleys and other drive components for more than 80 years. If this pulley is part of a machine that is down, send us the part number by WhatsApp and we will help you find the solution. We work with factories, plants and maintenance teams throughout Argentina.
