The POLEA 400 1B industrial pulley is a power transmission component mounted on a machine shaft to drive a section B V-belt. With a 400 mm diameter and a single groove, it is used in drives that require a simple transmission ratio and good belt wrap. It is in-house manufacturing, EMMAR brand, which allows the machining to be adjusted to the equipment's needs.

This item is a pulley with a 400 mm diameter, 1 groove and section B. The POLEA 400 1B designation summarizes those three variables: the outside diameter, the number of grooves and the belt profile it accommodates. Section B corresponds to a classic V-belt profile, and the groove is machined so the belt seats at the correct angle. It is a cast iron or steel part, depending on the application, and is balanced to rotate without vibration at the usual working speeds.

It is used in machines that need to transmit power between parallel shafts: compressors, fans, centrifugal pumps, conveyor belts, mixers and factory equipment. It also appears in gear reducers and multipliers where a fixed ratio is required. Being single-groove, it is common in low or medium power drives, or in configurations where several pulleys are combined to achieve the desired total ratio.

To select it, take into account the pitch diameter, the belt width, the shaft diameter and the type of keyway. Check that the pulley is aligned with the driven pulley and that the belt tension is correct: an off-center pulley or a poorly tensioned belt shortens the life of the shaft bearings. If the equipment works with variable loads or frequent starts, it is advisable to review the service factor and balancing.

If you need a different size, we can manufacture a pulley with another diameter, another number of grooves or for another belt section. We can also machine the bore and keyway to match your machine's shaft. To do so, send us the part number POLEA 400 1B or the equipment data: diameter, grooves, section and shaft diameter. With that information we'll send you the quote and the manufacturing lead time.

MR Accesorios Industriales manufactures this pulley in its factory and sells it together with belts, bearings and housings. If you already have the part number, write to us on WhatsApp and we'll reply with the quote. If you are not sure about the size, send us a photo of the old pulley or the measurements taken with a caliper. That way we help you identify the correct part and avoid assembly errors.
