The 280 8C pulley is a V-belt drive pulley with section C, 280 mm diameter and 8 grooves. It is used to drive shafts from a motor, reducing or increasing speed depending on the combined diameters. It is in-house manufacturing, EMMAR Accesorios Industriales brand, so we produce it with the finish and balancing required by each application. If you need to replace a worn pulley or build a new drive, this model handles high power with several belts in parallel.
This item is a pulley with 280 mm diameter, 8 grooves and section C. The grooves are the seats where the V-belts rest; with eight of them, the pulley distributes the load across eight belts, which is common when transmitting significant power or when some redundancy is desired. Section C corresponds to a medium-to-large belt profile, and the 280 mm diameter defines the transmission ratio you will get depending on the pulley it runs against. It is an in-house manufactured part, EMMAR brand, not resold.
It is used in machine and equipment drives where power is transmitted by belts: compressors, fans, pumps, mills, conveyor belts, mixers and process equipment in general. It also appears in the field, in implements and agricultural machinery that run section C pulleys. With 8 grooves, it is common on the fast shaft of a machine driving a slow shaft with high torque, or the other way around, depending on how the pulley pair is set up.
To mount it, check that the bore and keyway match the shaft, and that the pulley is aligned with the one it runs against: misalignment, even small, punishes the belts and bearings. The number of belts to install depends on the power to be transmitted; you do not need to use all 8 grooves if the calculation calls for fewer, but all belts should work with the same tension. Check the condition of the grooves before mounting: burrs or wear change how the belt seats.
If you need a different diameter, a different number of grooves or a pulley for another belt type, it can be requested. The same if you are looking for an equivalent to a pulley you already have mounted: send us the outside diameter, number of grooves, section and bore diameter, and we will compare it with what we manufacture. We can also evaluate the material and treatment according to the working environment.
To request a quote for this 280 8C pulley or a variant, send the part number by WhatsApp to MR Accesorios Industriales. If you have doubts about the equivalence with the pulley you are replacing, send us a photo or the shaft data and we will help you define it. We have been working in the industrial sector for more than 80 years, so we can guide you on both the pulley and the belts and bearings of the equipment.

Frequently Asked Questions
- What does it mean that it has 8 grooves and section C?
- Eight grooves are the seats where the belts rest, and section C is the corresponding V-belt profile. That defines how many belts you can mount and what type of belt goes in each groove. If your drive uses another section, ask us.
- Can I order it with another diameter or a different number of grooves?
- Yes. Since it is in-house manufacturing, EMMAR brand, variants of diameter, number of grooves and bore can be evaluated. Send the data of the pulley you need and we will tell you if it falls within what we manufacture or if another configuration is better.
- How do I know if it replaces the pulley I have mounted?
- Compare outside diameter, number of grooves, belt section and bore diameter with keyway. With that data we confirm the equivalence. If you can, send a photo of the old pulley and the shaft by WhatsApp.
