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 driving pulley so that the belts work 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. With 4 grooves, it allows power to be distributed across 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 drive failure.

To mount it, check that the shaft and keyway are clean and free of burrs, and that the pulley fits without blows. 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 driving pulley to define the correct ratio.

If you need an equivalent pulley, 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 propose the pulley with similar characteristics or we manufacture it. We work with standard sizes and also with custom developments within the section C series.
