The 350 mm industrial pulley with 3 grooves, section B, is a power transmission component mounted on shafts to transmit motion by means of V-belts. Its diameter and number of grooves make it suitable for applications requiring a specific drive ratio and capacity for several belts in parallel. It is manufactured by EMMAR Accesorios Industriales, which since 1945 has produced pulleys and other components for the Argentine industrial market.

This item is a pulley with a 350 mm diameter, 3 grooves and section B. The designation POLEA 350 3B summarizes those characteristics: 350 mm outside diameter, 3 grooves and profile B. Section B corresponds to a type of V-belt widely used in medium-power industrial drives. The pulley is manufactured with materials and tolerances that ensure a correct fit on the shaft and precise alignment of the grooves.

It is used in machines and equipment that need to transmit power between parallel shafts, such as mills, mixers, compressors, pumps, fans and conveyors. It is also common in the agricultural and industrial sector for driving implements. Having three grooves allows the load to be distributed among several belts, which is useful when greater transmission capacity is required or when a certain redundancy is sought in case one belt breaks.

To correctly select this pulley, take into account the shaft diameter, the keyway type, the center distance and the power to be transmitted. It is essential to verify that the belt section matches profile B and that the number of grooves is adequate for the required power. During installation, ensure alignment between pulleys to avoid premature wear of belts and bearings. The pulley must be properly secured to the shaft, with no axial or radial play.
