The 360 7B pulley is a power transmission pulley of in-house manufacturing, EMMAR brand, with a 360 mm diameter and 7 grooves for section B belts. It is used to transmit motion between parallel shafts in industrial equipment, where speed must be multiplied or reduced and the load distributed among several grooves. Because it is in-house production, MR Accesorios Industriales can adjust the machining and balancing according to the application. It is designed for mounting on a shaft with a keyway and for working with section B V-belts.

This pulley has a 360 mm diameter, 7 grooves and section B. The designation POLEA 360 7B summarizes those three variables: the outer diameter, the number of grooves and the belt profile. Multiple grooves allow the power to be distributed among several belts, which reduces the load per groove and improves continuity of operation if a belt degrades. The machining of the grooves and the balancing are controlled so that the assembly rotates without vibrations at the usual section B speeds.

It is used in V-belt drives of machines and equipment: compressors, fans, pumps, mills, mixers, conveyor belts and production lines. It also appears in reducers and multipliers where a specific transmission ratio is needed. With 7 grooves, it is common in drives that require transmitting moderate to high power with a single driving or driven pulley, and in installations where the aim is to distribute the effort among several belts to extend the service life of the assembly.

To select it, take into account the pitch diameter, the number of grooves, the belt section and the shaft diameter with its keyway. Check the center distance and the available belt length so that the transmission ratio is the desired one. During assembly, align the pulleys, tension the belts according to the belt manufacturer's manual and check the parallelism of the shafts. Misalignment, even slight, accelerates wear of grooves and belts. If the pulley operates at high revolutions, the required balancing should be confirmed.

If you need a nearby size, a different number of grooves or a pulley for a different section, send us the part number and the drive data: diameter, grooves, section, shaft diameter and type of keyway. With that we can evaluate an in-house manufacturing alternative or an equivalent pulley within the MR line. We can also advise you if you are looking to replace an existing pulley and do not have the designation at hand: the main measurements and a photo of the part are enough.
