The 190 2A pulley is a V-belt drive pulley, manufactured by EMMAR Accesorios Industriales. It has a 190 mm diameter and two grooves for section A belts, which allows transmitting motion between shafts with a defined drive ratio. It is used in machines and equipment where revolutions need to be reduced or increased while maintaining belt grip. Since it is in-house manufactured, you can inquire about variations in diameter, number of grooves or finish according to your application.

This item is a pulley with a 190 mm diameter, 2 grooves and section A. The designation POLEA 190 2A summarizes those three variables: the 190 mm outer diameter, the two grooves where the belts rest, and section A, which defines the groove profile. The part is machined so that the grooves are aligned and centered with respect to the shaft, so that the belt runs without uneven wear. It is a general-purpose power transmission pulley, not a cable or chain pulley.

Typical applications are machine tools, compressors, fans, centrifugal pumps, conveyor belts and belt-driven equipment in general. In all those cases the 190 2A pulley allows coupling a motor to a driven shaft with a fixed drive ratio. Having two grooves, it accepts two section A belts in parallel, which distributes the load and improves drive continuity if one belt fails. It is also used to replace worn pulleys or to modify the speed of existing equipment.

To correctly select this pulley, take into account the pitch diameter your drive needs, the number of grooves and the belt section you already use. Verify that the shaft bore matches the shaft diameter and that the keyway is compatible. When mounting, align the pulleys with a straightedge or a laser to avoid misalignment, and tension the belt according to the belt manufacturer's recommendations. If the pulley will run at high revolutions, it is advisable to check the balance and the condition of the grooves.

If you need a pulley with another size, another number of grooves or a different section, you can request an equivalent or a nearby size. For that, send us the part number POLEA 190 2A or the full designation of the original pulley, along with the belt section, shaft diameter and number of grooves. With that data we can evaluate manufacturing a custom pulley or suggest the closest variant within the in-house manufacturing line, EMMAR brand.
