The POLEA 240 1B pulley is a power transmission component manufactured by EMMAR Accesorios Industriales. It is designed to be mounted on shafts and transmit motion through section B V-belts. With a 240 mm diameter and a single groove, it is suitable for applications requiring a simple and reliable transmission ratio. Its metal construction and precise machining ensure stable operation in industrial equipment. It is a key part in belt drive systems, and its correct selection directly impacts the efficiency and durability of the assembly.
This pulley has a size of 240 mm in diameter, 1 groove and section B. Section B corresponds to a standardized V-belt profile, which makes it easier to select the right belt. The 240 mm diameter defines the transmission ratio together with the driven pulley. The single groove allows one section B belt to be housed, and the groove is machined for a correct fit and uniform wear. It is an in-house manufactured pulley, EMMAR brand, which guarantees control over materials and tolerances.
Section B pulleys with a single groove are used in a wide variety of equipment: fans, centrifugal pumps, compressors, light belt conveyors, mixers and machine tools. They are common in installations where moderate power needs to be transmitted with a single belt, or as part of more complex systems with several pulleys. They are also used in agricultural and industrial equipment that requires simple maintenance and quick belt replacement. Their single-groove design simplifies mounting and reduces the weight of the assembly.
To correctly select this pulley, take into account the required pitch or outside diameter, the belt section (B in this case) and the number of grooves. Verify that the shaft diameter matches the pulley bore, which may require additional machining depending on the case. It is important to align the pulleys and tension the belt according to the belt manufacturer's recommendations to avoid premature wear. If you need to mount it on a shaft with a keyway, confirm the keyway dimensions and the hub length. The pulley can be balanced if the operating speed requires it.
If you need a similar pulley but with another size, number of grooves or section, we can manufacture it or find an equivalent.

Frequently Asked Questions
- What does section B mean in a pulley?
- Section B is a standardized V-belt profile. It defines the width and height of the belt that fits into the groove. Section B pulleys accept belts of that profile, and must not be used with belts of other sections because they do not seat correctly.
- Can I request a pulley with more grooves or a different diameter?
- Yes. MR manufactures custom pulleys. You can request the same pulley with 2, 3 or more grooves, or with another diameter. Send the specifications on WhatsApp and we will quote the manufacturing or an equivalent.
- How do I know if this pulley is compatible with my equipment?
- You need to verify the shaft diameter, the belt section (B), the number of grooves and the required outside or pitch diameter. With that data we can confirm compatibility. If you have doubts, send us a photo or the data of the original pulley.
