The POLEA 140 2B is an in-house manufactured power transmission pulley, EMMAR brand, with a 140 mm diameter and two grooves for section B belts. It is used to drive shafts and equipment from a motor, and is a key part in any transmission line. Because it is domestically produced, dimensions and finishes can be adjusted to the equipment's needs. If you are building or replacing a drive, this pulley gives you a reliable base for the assembly.

This item is a pulley with a 140 mm diameter, 2 grooves and section B. That combination defines how many belts you can mount and what type of profile fits in each groove. Section B is one of the most widely used in medium industrial transmission, and the two grooves allow the load to be distributed between two belts. The designation POLEA 140 2B summarizes those three data points: size, number of grooves and section. It is an in-house manufactured part, EMMAR brand, designed to be integrated into new equipment or to replace existing pulleys.

Typical applications appear in transmission lines in workshops, plants and process equipment: fans, compressors, pumps, conveyor belts and machine tools. It is also used in the field, in agricultural implements and in material handling equipment. In all cases, the pulley is mounted on a shaft and receives the belt coming from the drive pulley. Because it has two grooves, it is commonly seen in drives where greater grip or continuity of operation is sought if one belt fails.

To mount and select this pulley correctly, take into account the outer diameter, the number of grooves and the belt section. Verify that the shaft and keyway match the pulley bore, and that alignment with the drive pulley is square to avoid uneven wear. Belt tension also matters: too loose and it slips, too tight and it punishes the equipment's bearings. If you need to calculate the transmission ratio, start from the pulley diameters and the motor speed.

If the part number POLEA 140 2B is not exactly the one you are looking for, we can look at a nearby size or an equivalent. For that, it helps if you send us the diameter, the number of grooves, the section and, if possible, a photo or a drawing of the shaft. With that data we will review which in-house manufacturing option fits best. We can also evaluate finishes or special machining according to the use. The idea is for the pulley to fit the equipment without odd adaptations or downtime.
