The industrial pulley with an 800 mm diameter and 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 installing three belts 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 transmission 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 to 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 a nearby size, 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.
