The 330 2A pulley is a V-belt drive pulley, manufactured by EMMAR Accesorios Industriales. It has a 330 mm diameter and two grooves for section A belts, which allows transmitting motion between shafts with two belt lines in parallel. It is used in equipment where a stable transmission ratio and good drive capacity are required, such as fans, compressors, pumps and conveyors. Because it is in-house manufacturing, machining and balancing variants can be requested according to the application.

This item is a pulley with a 330 mm diameter, 2 grooves and section A. The designation POLEA 330 2A summarizes those three variables: the 330 mm outside diameter, the number of grooves (2) and the belt profile it houses, section A. The grooves are machined so that the V-belt seats correctly and runs without slipping. It is a power transmission part designed to be mounted on a shaft and to receive motion from another pulley by means of belts.

Typical applications of a 2-groove section A pulley are equipment that needs to transmit torque with a certain redundancy: if one belt fails, the other keeps driving until the machine can be stopped. It appears in centrifugal fans, screw compressors, centrifugal pumps, screens, belt conveyors and machine tools. It is also used as a replacement pulley in lines where section A is already defined and a worn pulley or one with damaged grooves needs to be replaced.

To correctly select this pulley, take into account the pitch diameter, the number of grooves, the belt section and the shaft diameter where it is mounted. Check that the driving and driven pulleys have the same belt section and that the center distance allows tensioning. During assembly, check the alignment between pulleys, the concentricity and the condition of the grooves: a groove with burrs or wear accelerates belt deterioration. If the pulley runs at high speed, balancing should be evaluated.

If you need an equivalent pulley or a nearby size, the most practical thing is to send us the part number POLEA 330 2A or the designation shown on the original pulley. With that data we can verify whether the 330 mm size, the 2 grooves and section A match what you are looking for, or whether it is better to move to another combination of diameter and grooves. We can also analyze variants of bore machining and keyway according to your machine's shaft.
