The 270 1A pulley is a V-belt drive pulley, section A, with an outside diameter of 270 mm and a single groove. It is used to transmit motion between parallel shafts in machines and industrial equipment, where a simple and reliable drive ratio is needed. MR Accesorios Industriales manufactures it locally, with dimensional control and balancing, so it fits without surprises during assembly.
This item is a 270 mm diameter pulley, with 1 groove and section A. The designation POLEA 270 1A summarizes those three variables: the outside diameter, the number of grooves and the belt profile. Section A corresponds to classic V-belts with a 13 mm top width, although the groove is machined to standard for that profile. It is a cast iron or steel part, with hub and keyway, ready to mount on a shaft. If you need to confirm the shaft diameter or the hub type, it is checked before manufacturing.
The typical applications of a 270 mm, single-groove pulley are varied: centrifugal fans, pumps, screw compressors, light conveyor belts, mixers and machine tools. It is also used in refrigeration equipment and in low-power drives where a simple speed reduction or increase is sought. Because it is in-house manufactured, the hub diameter, keyway or balancing can be adapted to the equipment. It is common to see it in installations that already have a similar pulley and need to replace it without modifying the rest of the system.
To correctly select a section A pulley, take into account the power to be transmitted, the shaft RPM and the pitch diameter. The 270 mm outside diameter is not the same as the pitch diameter: the belt rests on the bottom of the groove, so the effective circumference is somewhat smaller. Verify that the number of grooves matches the number of belts on the equipment. During assembly, make sure the keyway and shaft are clean, and that the pulley is aligned with the driven pulley to avoid uneven belt wear.
If you cannot find the exact size, we can manufacture a custom pulley with the diameter, number of grooves and section you need. We can also quote an equivalent pulley if you send us the original part number or the shaft and groove dimensions. To do that, send us a message via WhatsApp with the designation POLEA 270 1A or with the data of the pulley you want to replace. We will reply with the alternatives that best suit your equipment.
At MR Accesorios Industriales we manufacture pulleys, split plummer block housings and ANSI chains. That allows us to control the entire process and adjust details such as balancing or surface treatment. If your equipment runs with section A pulleys, we can help you keep the drive in good condition. Write to us via WhatsApp and send us the part number or dimensions; we will advise you so that the pulley is properly mounted and lasts as long as it should.

Frequently Asked Questions
- What does it mean that it is section A?
- Section A is a classic V-belt profile. The pulley groove is machined with the standardized angle and dimensions so that the belt rests correctly. It is not interchangeable with section B or Z pulleys, which have other groove dimensions.
- Can I request a pulley with a different shaft diameter?
- Yes. Because it is in-house manufactured, we can modify the hub diameter and keyway according to your shaft. Send us the exact shaft dimension and the number of grooves you need, and we will quote a custom pulley.
- How do I request a pulley equivalent to the one I have?
- Send via WhatsApp the part number of the original pulley or the dimensions: outside diameter, number of grooves, section and shaft diameter. With that data we will indicate the equivalent or manufacture it to measure. You can also attach a photo.
