The 190 4A pulley is a power transmission pulley of in-house manufacturing, EMMAR brand, designed to mount on shafts and receive V-belts of section A. With a 190 mm diameter and 4 grooves, it transmits motion between shafts reliably in industrial equipment. It is a key part in belt drive systems, where alignment and the number of grooves define the drive capacity. It is used in a wide variety of machines and production lines.
This item is a pulley with a 190 mm diameter, 4 grooves and section A. The designation POLEA 190 4A summarizes its three main data: size, number of grooves and the type of belt it accepts. Section A corresponds to classic V-belts with a narrow profile, suitable for medium power transmissions. Being of in-house manufacturing, EMMAR brand, dimensions and machining are controlled to ensure correct seating of the belts in the grooves.
Pulleys of this type are used in fans, compressors, pumps, conveyor belts and machine tools, among other applications. Their function is to transmit motion from a driving shaft to a driven one, maintaining the desired transmission ratio. Having 4 grooves allows the load to be distributed among several belts, which provides redundancy and greater drive capacity. They are common in installations where reliability and continuity of operation are required.
To correctly select a pulley, take into account the pitch diameter, the number of grooves, the belt section and the shaft diameter. Verify that the pulley is compatible with the type of belt you will use and that the keyway and fastening system are adequate. During assembly, ensure alignment between pulleys to avoid irregular wear of belts and bearings. Belt tension must be the one recommended by the transmission manufacturer.
