The 340 4C pulley is a V-belt drive pulley manufactured by EMMAR Accesorios Industriales. It has a 340 mm diameter, 4 grooves and section C, which makes it suitable for transmitting power in medium and high-load equipment. It is mounted on shafts and aligned with the drive pulley so that the belts run without premature wear. It is a key part in power transmission systems that demand continuity and low maintenance.
This pulley is identified as POLEA 340 4C and belongs to the section C series. Its main attributes are: 340 mm size, 4 grooves and section C. Section C corresponds to wide-profile V-belts, and the 4 grooves allow four belts to be mounted in parallel on the same pulley. The 340 mm diameter defines the transmission ratio when combined with another pulley in the system. It is an in-house manufactured part, EMMAR brand, designed for demanding industrial applications.
It is used in machines that need to transmit torque steadily: screw compressors, industrial fans, centrifugal pumps, mills, mixers and conveyors. It also appears in mining equipment, aggregate processing plants and low-speed, high-load drive systems. Having 4 grooves allows the power to be distributed among several belts, which reduces individual tension and improves the service life of the assembly. It is common in installations where the process cannot be stopped due to a transmission failure.
To mount it, check that the shaft and keyway are clean and free of burrs, and that the pulley fits without being struck. Alignment between pulleys must be careful: angular or parallel misalignment accelerates wear on the belts and grooves. Tension is adjusted according to the belt type and the center distance; excessive tension stresses the equipment's bearings. When selecting, take into account the power to be transmitted, the shaft rpm and the diameter of the drive pulley to define the correct ratio.
If you need an equivalent pulley or a nearby size, the most practical thing is to send us the full part number, the number of grooves and the section. It also helps to attach a photo of the original pulley or the data of the belt the equipment uses. With that information we check whether we have a pulley with similar characteristics or whether it is better to manufacture it. We work with standard sizes and also with custom developments within the section C series.

Frequently Asked Questions
- What does it mean that it is section C?
- Section C is a V-belt profile wider than sections A or B. It is used to transmit more power per belt. This pulley has 4 section C grooves, so you can mount up to four belts of that profile.
- How do I request an equivalent pulley or a nearby size?
- Send us the part number, section, number of grooves and diameter you need via WhatsApp. If you don't have the part number, send us a photo of the old pulley or the belt data. With that we look for an equivalent or evaluate manufacturing it.
- What should I check before mounting it?
- Check that the shaft and keyway are clean and free of burrs, and that the pulley fits without forcing. Verify alignment with the drive pulley and adjust belt tension according to the equipment manual. Poor alignment or tension shortens belt life.
