This EMMAR pulley, identified as 190 4C, is a V-belt drive component with a 190 mm diameter and four grooves cut for section C belts. It transfers power from a driving shaft to one or more driven shafts, and it is commonly selected when a single belt line would not be enough to carry the load. Since the pulley is made in-house, the bore, keyway and locking arrangement can be machined to match the shaft it will sit on.

The designation tells you the main dimensions: 190 mm diameter and four grooves in section C. Section C is a wide-pitch V-belt profile intended for higher power transmission relative to speed. With four belts running side by side, the load is shared, so each belt runs at lower tension and the drive as a whole can handle more capacity. The pulley is supplied with the bore and keyway prepared for the shaft where it will be installed.

Typical applications are machines that move heavy loads at medium or low speed: mills, mixers, screens, piston compressors, high-flow pumps, and drives on agricultural or industrial equipment. It also shows up where speed has to be stepped down from an electric motor or a combustion engine to the working shaft. Four grooves make it a common pick for drives that cannot rely on one belt.

When specifying, check the pitch diameter, groove count, belt section and shaft diameter together. The pulley mounts with a key and, depending on the setup, a set screw or a taper locking system. Alignment between pulleys and correct belt tension matter — misalignment speeds up wear on both belts and grooves. On equipment that runs with vibration, it is worth checking balance and the condition of the shaft bearings.

Other groove counts, diameters or belt sections can be produced to order. To ask for an equivalent, send the part number POLEA 190 4C or the item name through WhatsApp, together with your shaft diameter, keyway and belt section. With those details we can confirm which variant fits your machine.
