The industrial pulley, 340 mm, 7 grooves, section C is a power transmission component that is mounted on shafts to transmit motion by means of V-belts. Its diameter and number of grooves make it suitable for drives that require high torque capacity and controlled speed. Because it is in-house manufactured, EMMAR brand, the dimensions and balancing are controlled for stable operation in continuous service.

This item is a pulley with a 340 mm diameter, 7 grooves and section C. The designation POLEA 340 7C summarizes those three variables: size, number of grooves and belt profile. Section C corresponds to type C V-belts, and the 7 grooves allow several belts to be mounted in parallel on the same disc. The grooves are machined so that the belts seat uniformly and transmit without slipping.

It is used in belt drive lines where speed needs to be reduced or increased between a drive shaft and a driven shaft. It appears in mining equipment, aggregate plants, mills, mixers, industrial fans and conveyors. Also in agricultural machinery and in drives of large-flow centrifugal pumps. The combination of 340 mm and 7 grooves makes it suitable for medium and high power, with good heat dissipation and less vibration than a smaller-diameter pulley.

To select correctly, verify the required outside diameter, the number of grooves and the belt section you already use. Check the central bore, the keyway and the shaft fastening system, which can be a taper mandrel or bushings. Check the alignment between pulleys and the belt tension: an off-center pulley accelerates wear of grooves and belts. If the equipment works with reversing rotation or pulsating loads, it is advisable to evaluate the balancing and the mass of the assembly.

If you need a pulley with a different number of grooves, another diameter or a different section, it can be manufactured to measure. To request an equivalent or a nearby size, send the part number POLEA 340 7C or the data of the original pulley: diameter, grooves, section, shaft diameter and type of fastening. With that data the feasibility is verified and the quote is prepared. Compatible bushings and belts can also be supplied to complete the transmission assembly.

MR Accesorios Industriales manufactures this pulley in its workshops and sells it along with the rest of the power transmission line. If you have doubts about the equivalence with an existing pulley, send a photo or a sketch with the main measurements. The technical team reviews the case and replies with a proposal.
