The 800 mm industrial pulley with 3 grooves for section C belts is a power transmission component that is mounted on a machine shaft to drive it by means of V-belts. It is used in equipment that needs to transmit torque with several belts in parallel, such as mills, mixers, compressors, high-flow pumps and industrial fans. Its large diameter allows reducing the revolutions of the driven shaft while maintaining load capacity.
This item is a pulley with an 800 mm diameter, 3 grooves and section C, according to the designation POLEA 800 3C. Section C corresponds to wide-profile V-belts, and the three grooves allow three belts to be installed in parallel on the same pulley. That multiplies the transmitted power without increasing the diameter. The part is manufactured at MR Accesorios Industriales and is machined so that the grooves have the angle and depth required by the section C belt.
Typical applications appear in machines that turn at low revolutions and need high torque: mills, horizontal mixers, screw compressors, high-flow centrifugal pumps, induced draft fans and chain conveyors. It is also used as a reduction pulley in drive lines where the motor turns fast and the working equipment turns slowly. In all cases, the pulley works together with a shaft, keyway and fastening system that must be in good condition.
To mount and select this pulley, first check the shaft diameter and the type of fastening —keyway, taper bushing or set screw—, because the pulley is machined according to that data. Then check the center distance and the available belt length: with an 800 mm diameter, the belt length changes considerably compared with a smaller pulley. Align the pulleys with a straightedge or laser and tension the belts according to the belt manufacturer's manual. A misaligned pulley wears the grooves and shortens belt life.
If you need another diameter, another number of grooves or a pulley for section B or D belt, manufacturing can be evaluated. We can also analyze the replacement of an existing pulley if you send us the outside diameter, the shaft diameter, the number of grooves and the belt section. To request an equivalent or a special size, send the part number POLEA 800 3C by WhatsApp to MR Accesorios Industriales and we will quote it.
MR Accesorios Industriales manufactures this pulley and other power transmission parts in its workshops. If your machine has a damaged pulley or you need a different configuration, write to us by WhatsApp with the part number and the shaft data. We will reply with the quote.

Frequently Asked Questions
- What does it mean that it is section C?
- Section C is the V-belt profile that fits into the grooves of this pulley. It is not a measurement of the pulley itself, but of the type of belt that must be used. If you have doubts, send us the belt part number and we will verify it.
- Can I order it with a different shaft diameter?
- Yes. The pulley is machined according to the shaft diameter and type of fastening. Send the shaft diameter by WhatsApp, whether it has a keyway or taper bushing, and we will quote the part with the size you need.
- Can it be used to replace a pulley of another brand?
- In many cases, yes. To confirm it we need the outside diameter, the number of grooves, the belt section and the shaft diameter of the original pulley. With that data we evaluate the replacement and send you the quote.
