The 210 3C pulley is a V-belt drive pulley, section C, with a 210 mm diameter and three grooves. It is used to transmit power between parallel shafts in industrial equipment, where a stable transmission ratio and good drive capacity are required. Because it is in-house manufacturing, EMMAR brand, the groove machining and balancing are controlled, two points that define belt service life and the vibration level of the assembly.

This item is a pulley with a 210 mm diameter, 3 grooves and section C. The designation POLEA 210 3C summarizes those three variables: size, number of grooves and belt profile. Section C corresponds to wide-profile V-belts, suitable for transmitting medium and high power relative to the diameter. The machining of the grooves defines belt support and alignment between pulleys, factors that directly affect wear and drive performance.

It is used in machines with electric motors and parallel shafts: compressors, fans, centrifugal pumps, conveyor belts, mixers and process equipment. It also appears in field drives, such as irrigation pumps and agricultural equipment, where the section C pulley with several grooves makes it possible to cover significant power without resorting to chains or gears. In all those cases, the pulley works together with a shaft, a keyway and a fastening system that must be respected.

To select correctly, take into account the pitch diameter, the number of grooves and the belt section. The 210 mm, 3-groove pulley is chosen when the power to be transmitted and the shaft speed allow it. Verify the shaft diameter, the type of fastening (keyway, taper bushing or set screw) and the alignment with the drive pulley. Misalignment, even slight, accelerates belt wear and generates vibration. Balancing also matters in high-speed applications.

If you need a different size or an equivalent pulley, send us the part number POLEA 210 3C or the diameter, number of grooves and section you use. With that data we can locate the pulley that best fits your drive. We can also guide you if you have to replace an existing pulley and do not have the technical data sheet. The idea is that you do not buy more or less than you need: the right pulley for your equipment.
