The 180 4B pulley is a V-belt drive pulley with section B, four grooves and 180 mm diameter. It is used to transmit power between parallel shafts in industrial machines and equipment, where speed must be increased or reduced and the load distributed among several belts. As an in-house manufactured product, EMMAR brand, variants of machining and balancing can be requested according to the application.
This item is a pulley with a 180 mm diameter, 4 grooves and section B. The designation POLEA 180 4B summarizes those three data: the 180 mm outside diameter, the number of grooves (4) and the belt section it accommodates, B. The grooves are machined so that section B V-belts seat evenly and transmit torque without slipping. It is an in-house manufactured part, EMMAR brand, designed to be mounted on standard shafts with keyway.
It is used in power transmissions of equipment such as compressors, fans, centrifugal pumps, mills, conveyor belts and machine tools. It also appears in reducers and multipliers where a fixed transmission ratio and simple maintenance are needed. Having four grooves allows the load to be distributed among several belts, which reduces the tension on each one and improves continuity of operation if one belt fails.
To select it, take into account the shaft diameter, the type of keyway, the center distance and the desired transmission ratio. Verify that the belt section matches that of the pulley and that the number of grooves is adequate for the power to be transmitted. Balancing and concentricity influence the service life of belts and bearings, especially at high speeds. If the shaft has a large diameter, it is advisable to evaluate a hub with greater thickness.
If you need a nearby size, a different number of grooves or a pulley for a different section, send us the part number POLEA 180 4B or the full designation by WhatsApp. With that data we can offer you an equivalent alternative. We can also guide you on the machining of the bore and the keyway according to the shaft you have. The more data you send us, the more accurate the proposal will be.
MR Accesorios Industriales manufactures this pulley and sells it together with belts, bearings and housings to assemble the complete drive. If you already have the old pulley, send us its measurements or a photo and we will compare it with the designation. Write to us on WhatsApp and we will quote the 180 4B pulley or the variant you need.

Frequently Asked Questions
- What does POLEA 180 4B mean?
- It means a pulley with a 180 mm diameter, with 4 grooves for a section B belt. It is a designation that summarizes the three main variables: diameter, number of grooves and belt section. It serves to identify the part unambiguously when ordering it or comparing it with another.
- What type of belt does this pulley use?
- It uses section B V-belts. The number of grooves is four, so you can mount up to four belts of that section. It is important that all belts are of the same brand and in good condition so that the load is distributed evenly.
- How do I request an equivalent pulley or a different size?
- Send by WhatsApp the part number POLEA 180 4B or the full designation, together with the shaft diameter and the type of keyway. With that data we will quote an equivalent pulley or a nearby size, according to what you need for your machine.
