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

This item is a pulley with a 380 mm diameter, 3 grooves and section C. The designation POLEA 380 3C summarizes those three variables: the outside diameter, the number of grooves and the belt profile it accepts. Section C corresponds to wide-profile V-belts, the ones used when power must 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 the drive of 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, it is advisable that the shaft and pulley 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 will use. Verify that the belt section is C and that the quantity matches the available grooves. Alignment between driving and driven pulleys is key: angular or parallel misalignment accelerates wear on belts and 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, the most practical thing is to send us the complete part number, the number of grooves and the belt section you are using. With that data we propose the pulley from our manufacturing that fits or we manufacture 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.
