The 190 4C pulley is a V-belt drive pulley manufactured by EMMAR Accesorios Industriales. It has a 190 mm diameter and 4 grooves for section C belts, which allows transmitting power from a drive shaft to one or several driven shafts. It is used in machines that need several belt lines to distribute the load, such as mills, mixers, compressors and process equipment. Because it is in-house manufactured, the bore, keyway and fastening system can be machined according to the equipment's needs.

This pulley has a 190 mm diameter and 4 grooves for section C belts. Section C corresponds to a wide-pitch V-belt profile, suitable for transmitting high power relative to speed. The four grooves allow distributing the load among several belts, so that each one works with lower tension and the assembly gains transmission capacity. The pulley is manufactured by MR and is supplied with the bore and keyway according to the shaft on which it is mounted.

It is used in equipment where significant loads must be moved at medium or low speeds: mills, mixers, screens, piston compressors, high-flow pumps and drives of agricultural or industrial machinery. It also appears in installations where speed must be reduced from an electric motor or a combustion engine to the working shaft. Having four grooves, it is common in drives that cannot depend on a single belt.

To choose it correctly, take into account the pitch diameter, the number of grooves, the belt section and the shaft diameter. The pulley is mounted with a key and, depending on the case, with a set screw or taper locking system. It is advisable to verify the alignment between pulleys and the belt tension: misalignment accelerates wear on the belt and the grooves. If the equipment operates with vibration, check the balance and the condition of the shaft bearings.

If you need a pulley with a different number of grooves, another diameter or a different section, it can be custom manufactured.
