The POLEA 140 3B pulley is a V-belt drive pulley, manufactured by EMMAR Accesorios Industriales. It has a 140 mm diameter and 3 grooves for section B belts. It is used to transmit power between parallel shafts in industrial machines and equipment, and is part of the power transmission line that MR has been supplying for more than 80 years. Its in-house manufacturing allows the machining to be adapted to the equipment's needs.

This item is a pulley with a 140 mm diameter, 3 grooves and section B. The POLEA 140 3B designation 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 most widely used in medium-power drives. Because it is in-house manufactured, 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. Having 3 grooves allows the load to be distributed among several belts and reduces the stress on each one. It is commonly found 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. Check that the shaft and keyway match the pulley bore, and that the 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, a nearby size or a different number of grooves can be evaluated.

If you are looking for an equivalent or a pulley of another size, send us the original part number, the number of grooves and the belt section. It also helps if you tell us the outside or pitch diameter and the shaft diameter. With that data, at MR Accesorios Industriales we can guide you toward the closest option within the in-house manufacturing line or among the brands we carry.
