The 130 4A pulley is a V-belt drive pulley, manufactured by EMMAR Accesorios Industriales. It has a 130 mm diameter, 4 grooves and section A. It is used to transmit motion between parallel shafts in industrial machines and equipment, where a defined transmission ratio is needed and multiple grooves are required to distribute the load. Because it is in-house manufactured, machining and balancing variants can be requested according to the application.

This pulley has a 130 mm diameter, 4 grooves and section A. Section A corresponds to classic narrow-profile V-belts, and the 4 grooves allow up to four belts to be mounted on the same pulley to distribute the transmitted power. The 130 mm diameter defines the transmission ratio when combined with another pulley in the same system. It is a cast iron or machined steel part, with ground grooves so the belt seats evenly and does not slip.

It is used in drives for machine tools, compressors, fans, pumps, conveyor belts and process equipment. It also appears in the drive of mills, mixers and elevators. In general, it is mounted on a shaft with a keyway and secured with a set screw or with a taper bushing, depending on the equipment design. When the system has several belts, the 4-groove pulley allows continued operation with fewer belts if one breaks, until it is replaced.

To choose it correctly, check the outside or pitch diameter your machine needs, the number of grooves and the belt section. Section A is not interchangeable with other sections: if the belt is B or SPZ, the pulley will not work. Also check the shaft diameter, the type of fastening and the balancing required if the speed is high. During assembly, align the pulleys with a straightedge or laser and tension the belts according to the equipment manual to avoid premature wear.

If you cannot find the exact size, a pulley with another diameter, another number of grooves or a different section can be requested. For that, send us the part number of the original pulley, a photo of the part and the shaft data: diameter, keyway and fastening system. It also helps if you indicate the belt you use and the center distance. With that data, at MR Accesorios Industriales we evaluate the in-house manufacturing of an equivalent pulley or a nearby size that fits the equipment.
