The 380 mm industrial pulley with 3 grooves, C section, is a power transmission component mounted on a machine shaft to transmit motion through V-belts. It is used in equipment that needs to move large loads with several belts in parallel, such as mills, mixers, compressors or high-flow pumps. MR Accesorios Industriales manufactures it in the country, with dimensional control on every part.

This item is a pulley with a 380 mm diameter, 3 grooves and C section. The designation POLEA 380 3C summarizes those three variables: the outer diameter, the number of grooves and the belt profile it accepts. C section corresponds to wide-profile V-belts, the ones used when power has to be transmitted with few belts. The three grooves allow the load to be distributed among three identical belts, which reduces the stress on each one and improves drive continuity.

Typical applications of a pulley of this size are in driving machines with high and sustained demand: mills, crushers, industrial mixers, screw compressors, high-flow centrifugal pumps and process fans. It is also found in lifting and conveying equipment, such as belts and bucket elevators, where a stable transmission ratio and low maintenance are needed. In all cases, the shaft and the pulley should be aligned so that the belts work evenly.

To select and mount this pulley, take into account the shaft diameter, the type of keyway and the fastening system you are going to use. Check that the belt section is C and that the quantity matches the available grooves. Alignment between drive and driven pulleys is key: angular or parallel misalignment accelerates wear on the belts and the grooves. Also check the initial tension, because a loose belt slips and one that is too tight stresses the equipment bearings.

If you need an equivalent pulley or a nearby size, the most practical thing is to send us the full part number, the number of grooves and the belt section you are using. With that data we can verify whether there is a pulley from our manufacturing that fits or whether it is better to make it to measure. We can also advise you on the shaft diameter and the type of bushing or hub that best suits your machine, without needing to change the rest of the drive.

MR Accesorios Industriales manufactures this pulley and other power transmission parts, and sells them together with belts, bearings and housings.
