The 550 3A pulley is a V-belt drive pulley manufactured by EMMAR Accesorios Industriales. It has a 550 mm diameter, 3 grooves and section A. It is used to transmit power between parallel shafts in industrial equipment, with the advantage that, being in-house manufactured, we can adjust machining details to suit your needs. It is a key part in the maintenance of production lines, mills, pumps and fans.

This item is a pulley with a 550 mm diameter, 3 grooves and section A. The designation POLEA 550 3A summarizes those three variables: the outer diameter, the number of grooves and the belt profile it accepts. Section A corresponds to classic narrow-profile V-belts, widely used in industrial power transmissions. Being in-house manufactured, EMMAR brand, we control the groove machining and balancing so that the pulley runs aligned and without vibration.

Typical applications for a pulley of this size and number of grooves are equipment that needs to transmit torque with several belts in parallel: industrial fans, centrifugal pumps, compressors, mills, mixers and conveyors. The 3 grooves allow the load to be distributed among three belts, which reduces the stress on each one and improves the reliability of the assembly. It is also used as a replacement pulley in machines where a 3-belt section A configuration already exists.

To properly mount and select this pulley, take into account the shaft diameter, the type of keyway and the fastening system (set screw, taper or plate). Verify that the driving and driven pulleys are aligned and that the center distance allows correct tensioning. The number of grooves must match the number of belts you are going to use. If you need to change the transmission ratio, we can evaluate the most suitable diameter and grooves together.

If you are looking for an equivalent or a nearby size, send us the part number POLEA 550 3A or the designation shown on your equipment. We can manufacture the pulley with another diameter, another number of grooves or adapt it to a different shaft. We can also quote the complete assembly with the corresponding section A belts. For that, send us the shaft data, the power to be transmitted and the working rpm, and we will advise you.

At MR Accesorios Industriales we have been manufacturing pulleys and other power transmission components for more than 80 years. If this pulley is not exactly the one you need, write to us on WhatsApp with the part number or a photo of the part and we will help you find the solution. We are in Buenos Aires, Argentina, and we serve the entire country.

Frequently Asked Questions

What does it mean that it is section A?
Section A is a classic V-belt profile. The pulley has its grooves machined with the angle and dimensions so that this belt seats correctly. It is not compatible with other profiles such as B, C or 5V without changing the pulley.
Can I order it with another diameter or number of grooves?
Yes, being in-house manufactured, EMMAR brand, we can machine the pulley with the diameter, number of grooves or bore you need. Send us your shaft measurements and the desired configuration by WhatsApp and we will quote you.
How do I know if this pulley replaces the one I have mounted?
Compare the outer diameter, the number of grooves and the belt section. Also check the bore diameter and the keyway. If you have doubts, send us a photo or the part number of the original pulley and we will help you verify it.
