The 160 mm industrial pulley with 3 grooves, section C, is a power transmission component that mounts on a machine shaft to receive a V-belt. Its function is to transmit rotary motion and regulate speed between the motor and the driven equipment. With three grooves, it allows the load to be distributed across several belts, which is useful in applications requiring greater drive capacity or backup in case one belt fails. It is manufactured by EMMAR Accesorios Industriales, which since 1945 has produced bearing housings, chains and pulleys for the Argentine industrial market.

This pulley has an outside dimension of 160 mm, three grooves and section C. Section C corresponds to an industrial-type V-belt profile, and the number of grooves indicates that it can hold three belts in parallel. The 160 mm diameter defines the working radius on which the belt rests, a key figure for calculating the transmission ratio together with the driven pulley. It is an in-house manufactured part, EMMAR brand, designed for mounting on standard shafts and for continuous-duty operation.

Typical applications of a three-groove section C pulley appear in equipment that needs to transmit power with a certain safety margin: screw compressors, industrial fans, centrifugal pumps, belt conveyors and machine tools. In these systems, using three belts distributes the load and keeps operation going if one of them wears out or breaks. It is also used in installations where the goal is to reduce the vibration and slippage that appear with a single belt.

To select this pulley correctly, take into account the pitch diameter, which is related to the outside dimension and the belt profile. Check that the keyway and the bore match the equipment shaft; if not, the bore can be machined as needed. Alignment between pulleys is essential to avoid irregular belt wear and noise. Also check that the belt section matches the pulley's section C, since a belt of another section will not seat correctly in the grooves.

If you need a pulley with a different number of grooves, another diameter or a different section, you can request an equivalent or a nearby size. For that, it is best to send the part number, the full designation or a photo of the original pulley with a ruler next to it. With that data, the technical team at MR Accesorios Industriales can identify the closest option within the in-house manufacturing line or evaluate a custom part. The more precise the information, the faster the response.

To request a quote for this pulley or ask about a variant, send the part number POLEA 160 3C by WhatsApp to MR. You can also indicate the number of grooves, the section and the diameter you need, and we will reply with the alternative that best fits your application. If you have questions about mounting or selection, the same channel can be used for the technical inquiry.
