The POLEA 400 2C pulley is an in-house manufactured industrial pulley, EMMAR Accesorios Industriales brand, designed to transmit power using section C V-belts. It has a 400 mm diameter and 2 grooves, which allows building two-belt drives in parallel to distribute the load. It is used in equipment that requires a stable transmission ratio and good traction capacity, such as fans, compressors, pumps and plant machinery. Being in-house manufactured, machining and balancing variants can be requested.

This item is a pulley with a 400 mm diameter, 2 grooves and section C. That combination defines the type of belt it accepts and the number of belts it can hold: two grooves for section C V-belts. The POLEA 400 2C designation summarizes those three data points: size, number of grooves and section. The part is manufactured at MR and machined to mount on the equipment shaft, with the bore and keyway according to the application. If you need to confirm the shaft diameter or the type of bushing, it is verified against a drawing or sample.

Typical applications for a pulley of this size are in medium and high-power belt drives: centrifugal fans, screw compressors, centrifugal pumps, screens, mixers and process lines. The 2 grooves allow using two section C belts in parallel, which improves running continuity if one belt wears or breaks. It is also used to reduce or increase speed between a motor and the driven equipment, depending on the diameters of the driving and driven pulleys.

To select and mount this pulley, take into account the power to be transmitted, the shaft rpm, the diameter of the driving pulley and the center distance. The number of grooves and the section must match the belts you are going to use. Check the alignment between pulleys, the belt tension and the condition of the grooves before starting up. Misalignment, even slight, accelerates wear on belts and equipment bearings. If there is vibration, it is advisable to evaluate the balancing of the pulley.

If you need a nearby size, a different number of grooves or a pulley for a different shaft, send us the POLEA 400 2C part number or the data you have: diameter, grooves, section and shaft diameter. With that we look for the equivalent or the manufacturing variant that best fits. We can also quote pulleys of other sections and diameters within the power transmission line. The idea is that you don't get stuck with a pulley that doesn't fit your equipment.

To quote this pulley or ask about a variant, write to us on WhatsApp and send us the POLEA 400 2C part number. If you have the shaft drawing or a photo of the old pulley, even better: that way we confirm bore, keyway and balancing before manufacturing. MR Accesorios Industriales works in power transmission and manufactures pulleys, split plummer block housings and ANSI chains, in addition to distributing bearings, seals and lubricants.
