The industrial pulley with a 300 mm diameter, one groove and section A is a power transmission component that is mounted on shafts to drive V-belts. It is used in machines that need to transmit torque with a single belt, such as fans, compressors, conveyor belts and factory equipment. Manufactured by MR, it is designed to last and maintain alignment in continuous service.

This item is a pulley with a 300 mm diameter, with 1 groove and section A. The commercial designation is POLEA 300 1A. Section A corresponds to narrow-profile V-belts, and the single groove simplifies mounting and tensioning. The 300 mm diameter defines the transmission ratio when combined with another pulley in the same system. MR manufactures it with dimensional control so that the belt seats evenly and does not come off.

It is used in equipment where there is a single belt run: axial and centrifugal fans, screw compressors, centrifugal pumps, light conveyor belts and machine tools. Also in factory installations that need to change the speed of a shaft simply. Being section A, it is common in small and medium powers, where a multi-groove pulley is not necessary.

To mount it, verify that the shaft has the correct diameter and key, and that the pulley bore matches. The pulley is fastened with a set screw or with a taper bushing, depending on the case. It is important to align the pulleys with a ruler or a laser to avoid uneven belt wear. Tension is adjusted following the belt manufacturer's recommendation. If the pulley works at high revolutions, it should be balanced.

If you need a different size, we can manufacture a pulley with another diameter, another number of grooves or another section. For that, send us the equipment data: pitch diameter, number of grooves, belt section and shaft diameter. We can also make the bore and keyway to measure. With that data we will provide you with a quote.

To order this pulley or an equivalent one, write to us via WhatsApp and mention the code POLEA 300 1A. If you have doubts about the section or diameter, send us a photo of the old pulley or the shaft measurements. At MR Accesorios Industriales we advise you so that the pulley is properly mounted and the transmission works without problems.

Frequently Asked Questions

What does it mean that it is section A?
Section A is a narrow-size V-belt profile. The pulley has the groove machined so that this belt fits and transmits motion. It is not compatible with belts of other sections, such as B or C, because the angle and width of the groove are different.
Can I order a pulley with more grooves?
Yes. We manufacture pulleys with the number of grooves you need. You only have to indicate how many grooves you want, the diameter and the section. We can also make the bore and keyway according to your machine's shaft. Send us the data and we will quote you.
How do I know if this pulley replaces the one I have?
Compare the outside or pitch diameter, the number of grooves and the belt section. If they match, it is likely to work. It is still advisable to verify the shaft diameter and the key. If you have doubts, send us a photo and the measurements via WhatsApp and we will help you.
