The 190 4B pulley is a power transmission pulley of in-house manufacturing, EMMAR Accesorios Industriales brand. It is designed to mount four section B belts and has a diameter of 190 mm. It is used to transmit motion between parallel shafts in industrial machines and equipment, where a stable transmission ratio is needed along with the possibility of adjusting speed by changing the diameter of the driving or driven pulley. Its metal construction and machined grooves ensure correct seating of the belts.

This item is a pulley with a diameter of 190 mm, with 4 grooves for section B belts. The designation POLEA 190 4B summarizes its characteristics: 190 mm outside diameter and 4 grooves for B belt. Section B corresponds to a belt profile with a top width greater than 16 mm, widely used in medium power transmissions. As it is of in-house manufacturing, EMMAR brand, dimensions and balancing are controlled for smooth operation.

Typical applications of a 4-groove section B pulley include industrial fans, screw compressors, centrifugal pumps, belt conveyors and machine tools. In all cases the goal is to transmit power with several belts to distribute the load and reduce vibration. It is also used in equipment where a fixed transmission ratio and simple maintenance are required, with the possibility of replacing belts individually without disassembling the entire assembly.

To mount this pulley, verify that the shaft has the appropriate diameter and keyway, and that the pulley is aligned with the driving pulley. Correct alignment prevents irregular wear of the belts and grooves. Belt tension must be the one recommended by the belt manufacturer; excessive tension overloads the bearings and low tension causes slippage. If you need to select a pulley for an existing transmission, take into account the power to be transmitted, the shaft rpm and the center distance.

If you are looking for an equivalent or a nearby size, the most practical thing is to send us the part number POLEA 190 4B or the diameter and number of grooves you need. We can also evaluate variants in section B with another diameter or number of grooves, or adapt the bore and keyway to your shaft. As it is in-house manufacturing, we have flexibility to adjust the machining according to your application. Ask us by WhatsApp and we'll send you the quote.
