The 190 3A pulley is a V-belt drive pulley, section A, with three grooves and a 190 mm diameter. It is used to transmit motion between parallel shafts in machines and industrial equipment, where speed needs to be multiplied or reduced according to the ratios between pulleys. Since it is in-house manufactured, EMMAR brand, you can inquire about machining and balancing variations according to the application.

This item is a pulley with a 190 mm diameter, 3 grooves and section A. The designation POLEA 190 3A summarizes those three characteristics: the 190 mm outer diameter, the number of grooves (3) and the belt profile it accepts, section A. It is designed to be mounted on shafts and transmit power through V-belts of that profile, which is one of the most widespread in low and medium power industrial drives.

Typical applications include machine tools, compressors, fans, centrifugal pumps, conveyor belts and process equipment in general. In all cases, the pulley is selected based on the desired drive ratio, the power to be transmitted and the available space. Having three grooves, it allows distributing the load among three belts, which reduces the tension on each one and improves the reliability of the assembly.

For mounting, verify that the shaft has the appropriate diameter and keyway length, and that the pulley is aligned with the drive pulley. Incorrect alignment causes irregular belt wear and vibrations. It is also important to check the balance, especially in applications with high speeds. If you need to define the pulley for existing equipment, the most practical approach is to start from the diameter, number of grooves and belt section you already have.

If you cannot find the exact size or need a pulley with another diameter, number of grooves or section, we can evaluate an alternative within the in-house manufacturing line. For that, it is advisable to send us the current part number, a photo or a sketch with the main dimensions: outer diameter, shaft diameter, overall width, number of grooves and belt section. With that data we can verify the feasibility of manufacturing an equivalent pulley.

To request a quote for this pulley or inquire about a variant, send us the part number POLEA 190 3A by WhatsApp. If you have doubts about the section or the number of grooves, we can also help you interpret the designation of the pulley you need to replace. MR Accesorios Industriales manufactures this line and can provide technical advice so that the pulley is correctly specified.
