The MR industrial pulley, 320 mm, 1 groove, section A, is a power transmission component manufactured by MR Accesorios Industriales. It is used to mount on shafts and transmit motion via V-belts of section A. Its single-groove design makes it suitable for simple drives where a fixed transmission ratio is required. Because it is in-house manufactured, dimensions and features can be adapted to the equipment's needs. It is a key part in machines that run with belts of this section.
This MR pulley measures 320 mm in diameter, with one groove and section A. It is manufactured by MR, which ensures control over the production process and the ability to adjust dimensions or construction details. Section A corresponds to a standardized V-belt profile, suitable for transmitting moderate power in a single groove. The 320 mm diameter allows a specific peripheral speed depending on the shaft RPM. It is a robust part, designed for continuous service in industrial environments.
Typical applications include machine tools, compressors, fans, centrifugal pumps, conveyors and transmission equipment in general. In all cases, it is used together with section A belts and, frequently, with a smaller drive pulley to achieve the desired speed reduction or increase. It is also used in transmission systems where a single belt is required, whether due to space limitations or the power to be transmitted. It is common in installations that need simple maintenance and available spare parts.
For mounting, check that the shaft has the correct diameter and tolerance, and that the keyway matches the pulley's. It is essential to correctly align the drive and driven pulleys to avoid premature belt wear and vibration. Belt tension must be the one recommended by the machine manufacturer; excessive tension overloads the bearings and insufficient tension causes slipping. Before start-up, check the balancing and the fastening of the fixing elements. If you need technical assistance, contact MR Accesorios Industriales.
If you need a pulley with another size, number of grooves or section, we can manufacture it. To request an equivalent or a nearby size, send the code POLEA 320 1A or the features you need (diameter, grooves, section, shaft type) via WhatsApp. Our technical team evaluates feasibility and replies with a proposal. Because it is in-house manufacturing, we have flexibility to adapt to your requirements. We can also advise you on the most suitable pulley for your application based on power and working RPM.

Frequently Asked Questions
- What does it mean that it is section A?
- Section A is a standardized V-belt profile. This pulley is designed to work with belts of that section, which are suitable for transmitting moderate power in a single groove. It must not be used with belts of another section.
- Can I order a pulley with more grooves?
- Yes, because it is in-house manufacturing we can develop pulleys with the number of grooves you need. Send the specifications via WhatsApp: diameter, number of grooves, section and shaft type. We will quote a custom part.
- How do I know if this pulley is compatible with my machine?
- Check the shaft diameter, the keyway and the belt section your equipment uses. If they match this pulley's features, it is compatible. If in doubt, ask us with your machine data and we will advise you.
