The 340 5C pulley is a V-belt drive pulley, section C, with a 340 mm diameter and 5 grooves. It is used to transmit power between parallel shafts in industrial equipment, where a stable transmission ratio and good drive capacity are needed. It is in-house manufactured, EMMAR Accesorios Industriales brand, which allows the machining and quality of the assembly to be controlled. If you need to replace an existing pulley or build a new drive, this model can be combined with other pulleys of the same section to achieve the desired ratio.

This pulley has a 340 mm diameter, 5 grooves and section C. Its commercial designation is POLEA 340 5C and it belongs to the in-house manufacturing line, EMMAR brand. The grooves are machined to receive section C V-belts, which have the highest transmission capacity among classic belts. The 340 mm diameter defines the pulley's tangential speed for a given rotation rate, and the number of grooves determines how many belts can work in parallel to distribute the load. Being in-house manufactured, concentricity and balancing can be verified before dispatch.

It is used in machine and equipment drives where significant loads must be moved at moderate speeds: screw compressors, mills, mixers, high-flow centrifugal pumps, industrial fans and conveyors. It also appears in the drive of screens, conveyor belts and continuous process equipment. In all those cases, the 5-groove pulley allows adding belts to increase transmitted power without changing the diameter, which is useful when demand grows and the drive must be adjusted without replacing the entire assembly.

To mount this pulley, check that the shaft has a compatible diameter and keyway, and that the pulley is aligned with the drive pulley. Groove alignment prevents uneven belt wear and reduces vibration. When selecting, take into account the power to be transmitted, the shaft speed and the desired transmission ratio: with a 340 mm diameter and 5 section C grooves you can calculate how many belts you need and which complementary pulley is suitable on the other side. If space is limited, also check the outer diameter and the total hub width.

If you need a pulley equivalent to the 340 5C or a nearby size, the most practical thing is to send the part number or designation via WhatsApp. At MR Accesorios Industriales we can check whether there is a pulley with similar characteristics in the in-house manufacturing line or whether it is better to machine one to measure. We can also advise you on the complementary pulley to complete the drive. The more data you send — diameter, grooves, section and shaft type — the faster the response.

The 340 5C pulley is manufactured at MR with control of the critical dimensions: groove diameter, pitch and concentricity. This ensures that the belts seat properly and that the drive runs without slipping or premature wear. If you are building a new drive or replacing a worn pulley, send the part number POLEA 340 5C via WhatsApp and we'll quote you. MR Accesorios Industriales has more than 80 years in the field and manufactures housings, chains and pulleys for the Argentine industrial market.
