The industrial pulley 330 1A is an in-house manufactured power transmission pulley, EMMAR brand, with a 330 mm diameter, 1 groove and section A. It is used to transmit motion from a motor to a machine through a V-belt. Because it is in-house manufactured, MR controls the groove machining and balancing, which results in a pulley designed for continuous service in plants and workshops.

This item is a pulley with a 330 mm diameter, with 1 groove and section A. The designation POLEA 330 1A summarizes those three variables: size, number of grooves and belt section. Section A corresponds to classic V-belts with a narrow profile, and the single groove defines that it works with a single belt. The 330 mm diameter places it among the medium-large size pulleys within MR's sheet metal and hub line.

Typical applications are belt drives in low and medium power equipment: fans, centrifugal pumps, compressors, light conveyor belts, mixers and machine tools. It is also used as an output pulley on gear reducers and as a driven pulley in systems where the transmission ratio needs to be adjusted by changing the diameter. Because it has a single groove, it is common in simple assemblies, with a single belt run and tension adjustable from the motor.

To select and mount this pulley, verify that the belt is section A and that the 330 mm diameter is compatible with the desired transmission ratio and the available space. Check the alignment between the driving and driven pulleys: angular or parallel misalignment accelerates wear on the groove and the belt. The pulley is mounted on the shaft with a key and fixed axially; it is advisable to check the balancing if it will rotate at high speeds. Belt tension is adjusted according to the equipment manual.

If you need an equivalent or a nearby size, the most practical thing is to send us the part number POLEA 330 1A or the diameter and section you are looking for. We can also look at variants with a different number of grooves or nearby diameters within the same section A. If space is limited or the transmission ratio has changed, tell us the RPM of the motor and of the driven machine and we will guide you on the pulley that best fits.
