The 230 3A pulley is a V-belt drive pulley with section A, three grooves and a 230 mm diameter. It is used to transmit power between parallel shafts in industrial equipment, allowing speed adjustment through the ratio of diameters. It is an in-house manufactured part, EMMAR Accesorios Industriales brand, designed for mounting on keyed shafts and for use with section A profile belts. If you need to replace an existing pulley or build a new drive, this model covers medium-demand applications.

This item is a pulley with a 230 mm diameter, 3 grooves and section A. The designation POLEA 230 3A summarizes those three variables: the outer diameter, the number of grooves and the belt profile. It is manufactured by EMMAR, which allows control of groove machining and balancing. It mounts on cylindrical keyed shafts and is secured with a set screw or with a taper bushing system, depending on the case. Section A accepts classic V-belts of that profile, and the three grooves allow the load to be distributed among three belts.

Typical applications include fans, centrifugal pumps, screw compressors, belt conveyors and machine tools. In process plants, it is used to couple electric motors with gearboxes or with the final equipment. It also appears in extraction systems and in pumping equipment where a fixed transmission ratio is required. As a three-groove pulley, it is common in drives that require some redundancy or greater torque capacity without resorting to wider belts.

To select correctly, check the shaft diameter, the type of fastening and the center distance. The 230 mm pulley with section A is chosen when the peripheral speed and the power to be transmitted are compatible with that profile. It is important to align the pulleys and tension the belts according to the belt manufacturer's recommendations. If the pulley is mounted on a shaft with a taper bushing, respect the tightening torque. At MR we can advise you on the right number of grooves and diameter for your application.

If you need an equivalent pulley or a nearby size, the most practical thing is to send us the code POLEA 230 3A or the current dimensions: diameter, number of grooves and section. A photo of the mounted pulley or of the assembly also works. With that data, from MR Accesorios Industriales we will quote alternatives within the section A pulley line. If space allows, we can evaluate a different diameter or a different number of grooves to maintain the transmission ratio.
