The POLEA 320 3C pulley is an industrial pulley with a 320 mm diameter, with 3 grooves for section C belts. It is designed to transmit power in equipment that requires several belts in parallel, such as compressors, fans, mills or conveyor belts. Its construction is in-house manufacturing, EMMAR brand, which allows the machining to be adjusted to the mounting requirements. It is used both in new installations and in replacements where the original transmission ratio needs to be maintained.

This item is a pulley with a 320 mm diameter, 3 grooves and section C. The designation POLEA 320 3C summarizes those three variables: size, number of grooves and belt type. Section C accepts belts with a taller profile than sections A or B, so it is chosen when more power needs to be transmitted or when the center distance is limited. The three grooves allow the load to be distributed among several belts, which reduces the stress on each one and extends the service life of the assembly.

Typical applications for a 3-groove section C pulley appear in high-demand equipment: screw compressors, centrifugal fans, mills, mixers and conveyors. It is also used in agricultural machinery and pumping equipment where a robust transmission with low vibration is required. Having several grooves means the system better tolerates uneven belt wear and allows it to keep operating if one of them fails, although replacing the complete set is recommended.

To correctly select this pulley, take into account the pitch diameter, the number of grooves and the belt section. Check that the shaft and keyway match the pulley machining, and that the center distance allows tensioning. Alignment between drive and driven pulleys is key to prevent premature wear. If the pulley is mounted on a shaft with axial load, it is advisable to use a taper bushing or a fastening system that ensures concentricity.

If you need a different size or a pulley with a different number of grooves, you can ask about an equivalent. To do so, send us the current part number, the belt section, the diameter and the number of grooves. We can also evaluate variants in in-house manufacturing, EMMAR brand. The more data you give us, the faster we can reply with an alternative that suits your equipment.
