The 140 4B pulley is a V-belt transmission pulley, section B, with a 140 mm diameter and 4 grooves. It is used to transmit power between parallel shafts in industrial equipment, where speed must be increased or reduced and a stable transmission ratio maintained. It is an in-house manufactured part, EMMAR Accesorios Industriales brand, designed to be mounted on shafts with a keyway and to work with section B belts.

This item is a pulley with a 140 mm diameter, with 4 grooves and section B. The designation PULLEY 140 4B summarizes those three variables: the 140 mm outside diameter, the number of grooves (4) and the belt section it corresponds to (B). Because it is of in-house manufacturing, EMMAR brand, it is produced under our control and variants of machining can be requested, such as the bore diameter and the keyway, according to the shaft where it will be mounted.

Typical applications are belt transmissions in machines and equipment: fans, compressors, centrifugal pumps, conveyor belts, mixers and mills, among others. In all cases, the pulley is selected based on the power to be transmitted, the drive shaft speed and the driven machine's operating speed. The number of grooves defines how many belts work in parallel and, therefore, the transmission capacity of the assembly.

For mounting, check that the bore and the keyway match the shaft, and that the pulley is aligned with the driven pulley. Misalignment, even slight, accelerates wear on the belts and the grooves. It is also advisable to check the tension according to the belt type and the center distance. If you are replacing an existing pulley, use the diameter, the section and the number of grooves as a reference, and confirm the shaft diameter before ordering it.

If you need an equivalent, send us the part number PULLEY 140 4B by WhatsApp along with the equipment data: shaft diameter, keyway, number of grooves and belt section. With that we propose the pulley from our line that fits or we manufacture it to measure. We can also guide you if the available space limits the diameter or if you need a different number of grooves.
