The 480 1B pulley is a power transmission pulley of in-house manufacturing, EMMAR brand, with a 480 mm diameter and one groove for a section B belt. It is used to drive shafts by means of V-belts in industrial equipment where a defined transmission ratio is required. Its construction allows it to be mounted on shafts with a keyway and secured with set screws or taper bushings, depending on the equipment design. MR Accesorios Industriales manufactures and sells it with the technical assistance to choose the right pulley.

This pulley has a 480 mm diameter, 1 groove and section B. The designation 480 1B indicates those three characteristics: the outside diameter, the number of grooves and the belt profile. Section B corresponds to type B V-belts, which are used in medium-power transmissions. The groove is machined so that the belt seats correctly and transmits motion without slipping. It is a pulley of in-house manufacturing, EMMAR brand, designed to replace worn components or to build a new transmission.

It is used in machines that need to transmit motion between parallel shafts, such as mills, mixers, compressors, centrifugal pumps, fans and conveyors. It also appears in lifting equipment and in production lines where a speed reduction or increase is required. Due to its diameter, it is common in low-speed, high-torque applications, where the section B belt works with good grip. If the original equipment comes with a similar pulley, this size may be the direct replacement.

To mount it, check that the shaft has the diameter and keyway compatible with the pulley bore. The pulley is secured with set screws or with a taper bushing, depending on the case. It is important to align the pulleys to avoid irregular belt wear and vibration. Belt tension must be the one recommended by the equipment manufacturer; excessive tension stresses the bearings and low tension makes the belt slip. If you do not know the exact size, we can help you identify the pulley from the diameter, the width and the section.

If you need a pulley with a different number of grooves, another diameter or a different section, we can manufacture it or find an equivalent. To do so, send us the part number POLEA 480 1B or the data of the original pulley: diameter, number of grooves, belt section and shaft diameter. With that information we will quote the option that best suits your equipment. We can also advise you on mounting and the necessary accessories, such as bushings and keys.
