The 140 mm industrial pulley with 4 grooves for section C belts is a power transmission component that is mounted on a machine shaft to drive it by means of V-belts. It is used in equipment that needs to distribute power across several grooves or maintain a stable transmission ratio. It is in-house manufactured, EMMAR brand, which allows the machining to be adjusted to the size and keyway type required by each application.

This item is a pulley with a 140 mm diameter and 4 grooves for section C belts. Its commercial designation is POLEA 140 4C. Section C corresponds to a wide-pitch V-belt profile, suitable for transmitting medium and high power at moderate transmission ratios. The four grooves allow the load to be distributed across several belts, which reduces the stress on each one and improves drive continuity if a belt fails. The pulley is manufactured by MR and is machined according to the size and shaft type indicated by the customer.

It is used in belt drive applications where a small-diameter pulley with several grooves is required. It appears in compressors, pumps, fans, mills, conveyor belts and machine tools. It is also used in refrigeration equipment and in low-speed, high-torque drive systems. Having four grooves, it is common in installations where the aim is to distribute power across several belts to reduce wear and keep running if one of them breaks.

To select the pulley, take into account the pitch diameter, the number of grooves, the belt section and the shaft diameter. Verify that the keyway and the fastening system are compatible with the machine shaft. The pulley must be aligned with the driving pulley to avoid uneven belt wear. If space allows, choose a larger diameter to reduce belt bending and increase the service life of the assembly. Section C supports a power range that should be validated with the manufacturer's technical data sheet.

If you need a pulley with a different number of grooves, another diameter or a different section, it can be custom manufactured. To request an equivalent or a nearby size, send the part number POLEA 140 4C or the drawing with the shaft dimensions, the keyway and the distance between grooves. With that data, the technical team at MR Accesorios Industriales evaluates feasibility and sends you the quote. Pulleys of different sizes can also be combined in the same order to complete a drive system.

MR Accesorios Industriales manufactures this pulley in Argentina and sells it under its own brand. If you have doubts about compatibility with your equipment, send the part number by WhatsApp and we will advise you. The pulley is delivered machined according to each customer's requirements, with the option to define the keyway type and the surface finish. To get a quote, you only need the part number or the main shaft and belt dimensions.
