The 100 4B pulley is a V-belt drive pulley, manufactured by EMMAR Accesorios Industriales. It has a 100 mm diameter and 4 section B grooves, which allows power to be transmitted from a drive shaft to one or several driven shafts by means of belts. It is used in machines and installations that need reliable speed reduction or multiplication, with good load capacity and alignment. Because it is in-house manufactured, groove machining and balancing are controlled for stable operation.

This item is a pulley with a 100 mm diameter and 4 section B grooves. Section B corresponds to an industrial-type V-belt profile, and the 4 grooves allow up to four belts to be mounted in parallel on the same pulley. The 100 mm diameter is measured in the belt contact area, and the grooves are machined with the angle and depth corresponding to section B. It is an in-house manufactured part, EMMAR brand, designed for belt drives in equipment with parallel shafts.

Typical applications include machine tools, compressors, fans, centrifugal pumps, conveyors and process equipment. In all cases the aim is to transmit torque from an electric or combustion engine to the driven equipment, with the possibility of varying the drive ratio by changing the diameter of the drive or driven pulley. The number of grooves defines how many belts work in parallel: the greater the number, the greater the transmission capacity for the same diameter.

To select and mount this pulley, take into account the pitch diameter, the belt section, the number of grooves and the shaft diameter. Check that the keyway and the fit correspond to the shaft, and that the pulley is aligned with the drive pulley to avoid uneven belt wear. Belt tension must be adequate: low tension causes slipping and too much tension overloads the equipment's bearings. If the assembly runs at high revolutions, it is advisable to check balancing.

If you need an equivalent pulley or a nearby size, send us the part number POLEA 100 4B or the data of the original pulley: diameter, number of grooves, section and shaft diameter. We can also evaluate variants with a different number of grooves or nearby diameters within the same section B. The more data you send us, the faster we can confirm the equivalence and send you the quote.
