The MR industrial pulley, 350 mm with 3 grooves section A, is a power transmission component designed to be mounted on shafts and transmit motion via V-belts. It is manufactured in Argentina under MR Accesorios Industriales standards, with over 80 years of experience in the field. It is a key part in transmission systems that require multiple belt lines to distribute the workload.

This item is a pulley with a 350 mm diameter, 3 grooves and section A. The designation POLEA 350 3A summarizes those three variables: the 350 mm outside diameter, the number of grooves (3) and the belt profile it accepts, section A. It is designed to be mounted on shafts and transmit power through section A V-belts, which are the most widely used in light and medium industrial applications.

Typical applications include fans, centrifugal pumps, air compressors, belt conveyors and machine tools. In all these cases, the 3-groove pulley allows the load to be distributed among three belts, which reduces the individual stress on each one and provides redundancy: if one belt fails, the other two continue transmitting, albeit with lower capacity. It is commonly found in equipment that runs many hours a day and where operational continuity is important.

To select and mount this pulley, take into account the shaft diameter, the type of keyway and the fastening system (set screw, cone or bushing). Verify that the belt section matches section A and that the number of grooves is the one required for the power to be transmitted. The alignment between driving and driven pulleys must be careful to avoid premature wear of belts and bearings. If the pulley is mounted on a shaft that already has another pulley, check that they do not interfere with each other.

If you need a pulley with a different number of grooves, another diameter or a different section, we can manufacture it. MR Accesorios Industriales produces custom pulleys from drawings or samples. To do so, send us the part number POLEA 350 3A or the exact designation shown on your equipment, along with a sketch or a photo of the part. We can also help you identify the equivalent pulley if you are replacing an existing one.

To request a quote for this pulley or ask about a variant, write to us on WhatsApp and send us the part number POLEA 350 3A. We will reply with manufacturing alternatives. If you have doubts about the section or the grooves, send us a photo of the old pulley and the shaft dimensions; with that we can advise you.
