This item is a pulley with a 140 mm diameter, 3 grooves and section B. The designation POLEA 140 3B summarizes those three variables: size, number of grooves and belt profile. It is designed to be mounted on shafts and to receive section B V-belts, which are the widely used ones in medium-power transmissions. As it is in-house manufacturing, EMMAR brand, the groove machining and balancing are controlled according to the intended use.

It is used in power transmission equipment: fans, pumps, compressors, conveyor belts, mixers and machine tools. Also in installations where the speed ratio between a motor and a driven machine must be changed. As it has 3 grooves, it allows the load to be distributed among several belts and reduces the stress on each one. It is commonly seen in industrial plants, factories and continuous process equipment.

To select it, take into account the pitch diameter, the number of grooves and the belt section. Verify that the shaft and keyway match the pulley bore, and that alignment between pulleys is correct to avoid uneven wear. Belt tension is adjusted according to the equipment manual. If you need a different transmission ratio, an equivalent or a different number of grooves can be evaluated.

It also helps if you tell us the outside or pitch diameter and the shaft diameter. With that data, at MR Accesorios Industriales we will guide you within the in-house manufacturing line or the brands we sell.
