The 380 6B pulley is a V-belt drive pulley manufactured by EMMAR Accesorios Industriales. It has a 380 mm diameter and 6 grooves for section B belts. It is used to transmit power between parallel shafts in industrial equipment: fans, compressors, pumps, conveyor belts and production machines. Because it is in-house manufacturing, the bore, keyway and balancing can be machined according to the equipment's needs. If you need to replace an existing pulley or set up a new transmission, send us the part number by WhatsApp and we'll quote you.
This pulley has a 380 mm diameter, 6 grooves and section B. Section B is a classic narrow-pitch V-belt, suitable for medium power and moderate peripheral speeds. The 6 grooves allow the load to be distributed among several belts, which reduces the stress on each one and improves drive continuity if a belt fails. The 380 mm diameter defines the transmission ratio when combined with the driven shaft pulley. The part is manufactured at MR, so the bore and keyway machining is adjusted to the equipment shaft dimensions.
Typical applications of a 6-groove section B pulley are equipment that needs to transmit power continuously and with some reserve: industrial fans, screw compressors, centrifugal pumps, conveyor belts, mixers and machine tools. It is also used to replace worn or cracked pulleys in production lines. Because it has several grooves, it is commonly seen in drives where the goal is to reduce vibration and slippage, or where the equipment must keep running even if one belt breaks.
To mount this pulley, verify that the bore and keyway match the shaft. The pulley is fixed with a key and, depending on the case, with a set screw or taper bushing. It is important to align the pulleys with a straightedge or a laser so the belts run parallel and do not wear on one side. Belt tension is adjusted according to the equipment manual: too little tension makes them slip, and too much loads the shaft bearings. If the pulley will rotate at high speed, it should be balanced. At MR we can machine the bore, keyway and balancing according to the equipment data.
If you need a pulley equivalent to the 380 6B, send us the complete part number, the equipment brand and a photo of the part. With that data we can confirm whether the in-house manufactured pulley matches in diameter, grooves and section, or whether a nearby size is needed. We can also manufacture a custom pulley if the shaft or keyway are not standard. For that, send us the shaft diameter, the bore length and the number of grooves. The quote is made via WhatsApp with the part number MR-POLEA-B6-380 or with the designation POLEA 380 6B.

Frequently Asked Questions
- What does it mean that it is in-house manufacturing, EMMAR brand?
- It means that MR Accesorios Industriales manufactures the 380 6B pulley in its workshops. That allows the bore, keyway and balancing to be adjusted according to the equipment shaft. It is not a part bought from a third party and resold: it is produced with the dimensions the customer needs.
- Can I order a pulley with a different diameter or number of grooves?
- Yes. MR manufactures pulleys in different sizes and sections. If the 380 6B does not match your equipment, send us the diameter, the number of grooves and the belt section you use. With that data we will quote you a custom pulley or a nearby size from the series.
- How do I request a quote for the 380 6B pulley?
- Send the part number MR-POLEA-B6-380 or the designation POLEA 380 6B by WhatsApp. If you can, attach a photo of the old pulley and the shaft data. That way we confirm the size and send you the quote without hassle.
