The 120 5C pulley is a power transmission component that is mounted on shafts to receive section C V-belts. With 120 mm diameter and 5 grooves, it allows transmitting motion between parallel shafts in equipment that requires several belt lines. It is a part of in-house manufacturing, EMMAR brand, designed for industrial applications where robustness and precise alignment are needed.

This item is a pulley of 120 mm diameter, with 5 grooves and section C. The designation POLEA 120 5C summarizes those three variables: size, number of grooves and type of belt it houses. It is manufactured by EMMAR Accesorios Industriales, which since 1945 produces split plummer block housings, ANSI chains and pulleys. Section C corresponds to wide-profile V-belts, suitable for transmitting medium and high power in moderate transmission ratios.

It is used in machines that need to drive several mechanisms from the same shaft: compressors, pumps, fans, mills, mixers and belt transmission equipment in industrial plants. The 5 grooves allow distributing the load among several belts, which reduces individual stress and improves service continuity. It is common to find it in installations where a certain redundancy is required or where the torque to be transmitted is high.

To mount it, verify that the shaft has the correct diameter and key, and that the pulley is aligned with the driven pulley. Section C requires that the belts be of the same profile and length; mixing grooves with different belts accelerates wear. Check the tensioner and the center distance so that the contact arc is sufficient. If you need to replace an existing pulley, note the diameter, grooves and section before ordering the replacement.

If you cannot find the exact size, we can evaluate a pulley of a nearby diameter or with a different number of grooves within the same section C. For that, send us the code POLEA 120 5C or the data of the original pulley: diameter, grooves and section. We can also manufacture a custom pulley if the equipment requires it. The idea is that the transmission works without modifying the rest of the assembly.

At MR Accesorios Industriales we respond with the technical information you need to decide the purchase. If you have doubts about the section or the number of grooves, send us a photo of the old pulley and we will help you identify it.
