The 320 mm industrial pulley with 3 grooves, B section, is a power transmission component designed to be mounted on shafts and to receive V-belts. Its function is to transmit rotary motion between machines, allowing the speed ratio to be adjusted according to the diameter of the pulleys involved. It is a key part in belt drive systems, where reliability and good mechanical performance are required. MR Accesorios Industriales manufactures it with quality control and offers it for demanding industrial applications.

This pulley measures 320 mm in diameter, has 3 grooves and B section. It is manufactured by EMMAR, which guarantees that it meets the technical specifications for this type of component. The B section corresponds to a standard V-belt profile, and the 3 grooves allow up to three belts to be installed in parallel, which increases the power transmission capacity. The 320 mm diameter positions it as a medium-to-large pulley, suitable for specific transmission ratios.

Typical applications for this pulley include industrial machines such as compressors, centrifugal pumps, fans, mills, conveyor belts and process equipment in general. It is used in systems where power must be transmitted from an electric motor or a turbine to another piece of equipment, with the possibility of changing the speed by changing the ratio of diameters. It is also common in installations that require several belts to distribute the load and reduce the risk of slipping.

For mounting, it is essential to verify that the shaft has the correct diameter and length for the pulley's center bore, as well as the fastening system (keyway, set screw, etc.). Alignment between pulleys must be precise to avoid irregular belt wear and vibration. When selecting, the power to be transmitted, the rotation speed and the type of belt must be considered. The number of grooves and the section must match the pulleys in the system to ensure correct operation.

If you need a pulley with a different size, number of grooves or section, we can manufacture it or source an equivalent. For that, it helps if you send us the original pulley's part number, a photo or a sketch with the main dimensions: outside diameter, bore diameter, overall width, number of grooves and section. With that data, we can identify the part or develop a custom solution. MR Accesorios Industriales has experience in pulley manufacturing and can advise you technically.
