The 800 mm diameter, 4-groove, section C industrial pulley is a power transmission component designed to drive shafts using V-belts. It is used in equipment requiring high torque capacity and controlled speed, such as mills, conveyor belts and continuous process machines. Its robust construction allows aligning and tensioning the belts for stable operation in heavy-duty service.
This item is a pulley with an 800 mm diameter, 4 grooves and section C. The designation POLEA 800 4C indicates those three variables: size, number of grooves and the type of belt it accommodates. Section C corresponds to wide-profile V-belts, suitable for transmitting high power. Having four grooves allows the load to be distributed among several belts, which reduces the individual stress and improves the reliability of the drive.
It is used in applications where speed must be reduced and torque increased, such as mills, mixers, high-flow pumps, industrial fans and conveyors. It also appears in machine tools and continuous process equipment operating under demanding conditions. Due to its diameter, it is common in installations where radial space is not critical and transmission capacity is prioritized over compactness.
To mount it, verify that the shaft has the appropriate tolerance and that the keyway matches the pulley's. It is important to align the driving and driven pulleys to avoid uneven belt wear. The number of grooves must match the number of belts in the system; leaving grooves empty is not recommended if it was designed for four. Tension is adjusted according to the equipment manual or the belt manufacturer's recommendations.
If you need a pulley with a different size, number of grooves or section, we can manufacture it or find an equivalent. To do so, send us the outside diameter, shaft diameter, face width, number of grooves and belt section. With that data, we will guide you toward the closest option or develop a custom pulley. We can also advise you on mounting and the selection of compatible belts.
To request a quote for this pulley or ask about a variant, send the part number POLEA 800 4C by WhatsApp to MR Accesorios Industriales. If you have questions about the application, tell us which equipment it is mounted on and we will help you define the best option.

Frequently Asked Questions
- What does POLEA 800 4C mean?
- It indicates a pulley with an 800 mm diameter, with 4 grooves for a section C belt. It is an internal MR nomenclature to identify sizes and belt type. If you need another combination, it can be manufactured to order.
- What type of belt is it compatible with?
- It is designed for section C V-belts. It is important to use belts of that section so they fit correctly in the grooves and transmit power without slipping. Mixing sections is not recommended.
- How do I order a pulley with a different size?
- Write to us by WhatsApp with the data: outside diameter, shaft diameter, face width, number of grooves and belt section. With that we will assess whether a standard pulley or a special manufacturing is best.
