The pulley 50 1A is a power transmission pulley of in-house manufacturing, EMMAR Accesorios Industriales brand. It is designed to be mounted on shafts and receive a V-belt section A in a single groove. It is used in machines, equipment and production lines where motion needs to be transmitted between shafts simply and reliably. Its 50 mm diameter and single groove make it suitable for specific transmission ratios, with the advantage of being a locally manufactured part.
This item is a pulley with 50 mm diameter, 1 groove and section A. The designation POLEA 50 1A summarizes those three variables: diameter, number of grooves and the belt profile it accepts. Section A corresponds to a classic V-belt profile, widely used in light and medium industrial transmissions. As it is in-house manufacturing, EMMAR brand, the machining of the groove and the fit to the shaft are controlled according to the requirements of each application.
Typical applications of a single-groove, section A pulley are found in fans, centrifugal pumps, small compressors, light conveyors, machine tools and factory equipment. It is also used as a replacement pulley in existing installations where a damaged pulley needs to be replaced or the transmission ratio modified. In all cases, it is advisable to verify that the outside diameter and groove type are compatible with the belt and the available space in the machine.
To select and mount this pulley, take into account the pitch diameter, groove width, shaft diameter and fastening system. Section A requires the belt to seat correctly in the groove; if the groove is worn or the belt does not fit, the transmission loses efficiency and wear accelerates. Alignment between drive and driven pulleys is key: angular or parallel misalignment generates vibration, noise and premature belt wear. Also check belt length and center distance before mounting.
If you need an equivalent pulley or a nearby size, the most practical thing is to send the code POLEA 50 1A via WhatsApp along with the machine data: shaft diameter, belt section, number of grooves and current outside diameter. With that information, we can evaluate whether the same pulley or another configuration is suitable. MR Accesorios Industriales manufactures pulleys and also sells power transmission lines, so it is possible to compare alternatives within the same product category.
To request a quote for this pulley or ask about a variant, write to us via WhatsApp with the code POLEA 50 1A and your application data. If you have doubts about the section, number of grooves or diameter, send a photo of the original pulley or the shaft and belt measurements. That way we can confirm the right part and avoid mounting errors. Service is direct and technical, without intermediaries.

Frequently Asked Questions
- What does POLEA 50 1A mean?
- The code indicates a pulley of 50 mm diameter, with 1 groove and section A. Those three data define the size, the number of belts it accepts and the belt profile it works with. If your machine uses another section or more grooves, the corresponding variant can be found.
- How do I know if this pulley is compatible with my machine?
- Check the shaft diameter, the outside diameter of the current pulley, the belt section and the number of grooves. With that data, it is compared with the pulley 50 1A. If you have the original pulley at hand, send a photo and measurements via WhatsApp to confirm.
- Can I order a pulley with another size or number of grooves?
- Yes. MR manufactures pulleys in different configurations. Send via WhatsApp the code POLEA 50 1A and the machine data: shaft diameter, belt section, grooves and outside diameter. With that information, the most suitable alternative is evaluated and quoted.
