The POLEA 250 3A pulley is a power transmission component manufactured by EMMAR Accesorios Industriales. With a 250 mm diameter, 3 grooves and section A, it is designed to mount on shafts and transmit motion via V-belts. It is used in industrial machines, process equipment and transmission systems that require a multi-groove pulley to distribute the load. Its metal construction and precise machining ensure a correct fit and reliable operation in demanding applications.
The POLEA 250 3A is identified by its designation: 250 mm diameter, 3 grooves and section A. This configuration allows the use of section A V-belts, which are suitable for transmitting power across a range of medium speeds. The three grooves make it possible to mount multiple belts in parallel, which increases transmission capacity and provides redundancy in case one belt fails. The 250 mm diameter defines the transmission ratio when combined with other pulleys in the system. It is an in-house manufactured part, EMMAR brand, which guarantees control over materials and tolerances.
Typical applications for this pulley include machine tools, compressors, industrial fans, centrifugal pumps and transmission equipment in process plants. It is also used in belt drive systems where a three-groove pulley is required to distribute the load across several belts, reducing wear and extending the service life of the assembly. It is common in installations that need to adjust the rotation speed between a motor and a driven machine, while maintaining smooth and efficient operation.
For mounting, verify that the shaft has the correct diameter and length for the pulley's center bore, and that the keyway matches the shaft key. It is essential to align the pulleys in the system to avoid irregular belt wear and vibration. Belt tension must be as recommended by the belt manufacturer, neither too loose nor excessive. When selecting, consider the power to be transmitted, the rotation speed and the pitch diameter to calculate the correct transmission ratio. If you need guidance, the MR technical team can advise you.
If you need a pulley with a different number of grooves, a different diameter or a different section, you can ask about a nearby size or an equivalent. MR manufactures pulleys in various configurations, so it is possible to adapt the part to your requirement.
