The 140 3A pulley is a V-belt drive pulley of section A, with three grooves and 140 mm diameter. It is used to drive parallel shafts in industrial equipment, where power must be transmitted with a good speed ratio and stable running. Being of in-house manufacturing, EMMAR brand, the groove machining and balancing are controlled, two points that define belt life and the vibration level of the assembly.

This item is a pulley of 140 mm diameter, with 3 grooves and section A. These three data are what you need to check before replacing an existing pulley: the size defines the transmission ratio together with the driving pulley, the number of grooves defines how many belts work in parallel, and section A defines the belt profile that fits in the groove. The pulley is mounted on the equipment shaft and fixed according to the type of bushing or keyway it has.

Typical applications are fans, exhausters, centrifugal pumps, screw compressors, conveyor belts and factory machines. In all these cases the pulley works with a section A belt and transmits motion to another pulley of the same profile. When the equipment starts under load, the three grooves allow distributing the effort among several belts and reducing slippage, provided the alignment between pulleys is correct.

For mounting, check that the shaft has no burrs, clean the seat and respect the torque of the fixing screws. The pulley must be perpendicular to the shaft and aligned with the driving pulley: angular or parallel misalignment accelerates wear of the groove and the belt. It is also advisable to check belt tension using the deflection method and ensure that no groove has dents or burrs that could cut the cord.

If you need a nearby size or an equivalent, send us the code MR-POLEA-A3-140 or the diameter, number of grooves and section shown on the original pulley. With that data we look for the pulley that best suits your equipment, either from our manufacturing or within the power transmission line we sell. If space is limited, we can also evaluate a smaller diameter pulley with more grooves.

MR Accesorios Industriales manufactures this pulley in its plant and sells it together with belts, bushings and housings to assemble the complete set. If you have doubts about the pulley that corresponds to your equipment, write to us on WhatsApp with the part code or a photo of the old pulley and we will help you identify it.
