The 380 mm industrial pulley with 3 grooves for section B belts is a power transmission component mounted on shafts to transmit motion from a motor to a machine. Its diameter and number of grooves place it in medium-torque applications, where the load is distributed among several belts. MR Accesorios Industriales manufactures it locally, with dimensional control on every piece.

This item is a pulley with a 380 mm diameter, 3 grooves and section B. Its commercial designation is POLEA 380 3B and it belongs to the section B pulley series that MR manufactures. The three grooves allow installing three belts of the same profile, which distributes the effort and reduces the individual load on each belt. It is turned on a lathe to ensure concentricity and proper seating of the belts in the grooves.

Typical applications for a pulley of this diameter and three section B grooves are transmission equipment in industrial plants: fans, compressors, centrifugal pumps, conveyor belts and machine tools. It is also used in the field for agricultural implements and in factories that assemble or replace transmission systems. Because it is in-house manufactured, the bore and keyway can be adapted to the available shaft.

To correctly select this pulley, take into account the pitch diameter, the number of grooves and the belt section. Verify that the shaft where it is mounted has a compatible diameter and keyway, and that the opposite pulley maintains the desired transmission ratio. Alignment between pulleys is key to avoid premature wear of belts and bearings. If the system works with variable loads, tension should be checked periodically.

If you need a different diameter, a different number of grooves or a different section, we can manufacture it. Send us the part number POLEA 380 3B or the data of the shaft and the belt you will use, and we will quote an equivalent pulley or a nearby size within the same series. We can also make the bore and keyway to measure if you send us the drawing or the shaft dimensions.

To request a quote for this pulley or ask about a variant, write to us on WhatsApp at MR Accesorios Industriales with the part number POLEA 380 3B. We will reply shortly with the machining options. If you have doubts about the pulley you need, send us a photo or the assembly drawing and we will help you define the model.
