EMMAR POLEA 400 5B is a pulleys reference, within Power transmission. Request a quote for POLEA 400 5B via WhatsApp or email with the quantity you need; we respond promptly with lead time and equivalents.
The 400 5B pulley is a power transmission pulley of in-house manufacturing, EMMAR Accesorios Industriales brand, with a 400 mm diameter and 5 grooves for section B belts. It is used to transmit motion between parallel shafts in industrial equipment, where the load must be distributed across several grooves and a stable peripheral speed maintained. Its construction is designed for centering and balance to run with low vibration.
This item is a pulley with a 400 mm diameter, 5 grooves and section B. Those three data points define the mounting: the 400 mm diameter sets the transmission ratio together with the driven pulley, the 5 grooves allow the power to be distributed across five belts, and section B determines the belt profile it takes. The designation POLEA 400 5B summarizes those measurements in the order code.
It is used in transmission lines in industrial plants: fans, centrifugal pumps, compressors, mills, conveyor belts and process machines in general. It also appears in factory equipment and in assemblies where revolutions need to be reduced or increased with a large-diameter, multi-groove pulley, so as not to overload a single belt and to dampen starting peaks.
To select it, check that the belt is section B and that the number of grooves matches the power to be transmitted. Check the pitch diameter and the bore or bushing the shaft requires, because the pulley is mounted with the corresponding fastening system. Check the alignment between pulleys and the belt tension: misalignment wears grooves and belts even if the pulley is the right one.
If you need a nearby size, another diameter, another number of grooves or a pulley of a different section, send us the equipment data: driven pulley diameter, belt section, number of grooves, shaft diameter and mounting type. With that we look for the equivalent or the variant within the in-house manufacturing line, EMMAR brand.
To request a quote for this pulley or ask for an alternative, send the part number POLEA 400 5B by WhatsApp to MR Accesorios Industriales. If you have doubts about the replacement, attach a photo of the mounted pulley and the shaft measurement. That way we quickly confirm the variant that best suits your equipment.

Frequently Asked Questions
- What does 400 5B mean on the pulley?
- It means 400 mm diameter, 5 grooves and section B. Those data points define the belt it takes and the transmission ratio you can set up with the driven pulley.
- How do I request an equivalent pulley or a nearby size?
- Send the part number POLEA 400 5B by WhatsApp along with the equipment data: driven pulley diameter, section, grooves, shaft diameter and mounting type. With that we'll send you the variant or the equivalent.
- What should I check before mounting it?
- Check that the belt is section B, that the 5 grooves are in good condition, that the bore or bushing matches the shaft and that the alignment between pulleys is correct. Then adjust the belt tension.
