The POLEA 360 4C pulley is a V-belt drive pulley, section C, with a 360 mm diameter and 4 grooves. It is used to drive shafts from a motor, reducing or increasing speed depending on the combined diameters. It is in-house manufacturing, EMMAR brand, designed for equipment that runs many hours a day and needs a stable part, with aligned grooves and good support on the shaft.

This item is a pulley with a 360 mm diameter, 4 grooves and section C, according to its designation POLEA 360 4C. Section C corresponds to wide-profile V-belts, the ones used when a fair amount of power must be transmitted with few grooves. The 4 grooves allow the load to be distributed among four belts, so that each one works with less effort and the assembly has more backup. The 360 mm diameter defines the drive ratio when compared with the motor pulley.

It is found in machines in continuous use: screw compressors, industrial fans, mills, mixers, conveyor belts and pumping equipment. Also in drives where the goal is to reduce motor speed to reach a slower shaft with more torque. With 4 grooves, it is common in installations where you do not want to depend on a single belt and prefer the system to keep running even if one has to be replaced.

To mount it, check that the shaft and the keyway are clean and free of burrs, and that the pulley fits without being hit. Align the motor and shaft pulleys well: misalignment, even a small one, eats belts and generates vibration. Tension the belts according to the equipment manual and check the tension after the first hours of operation. If the drive carries a heavy load, it is best to use all 4 belts from the same batch and with the same wear.

If you need a different size, a pulley with a different number of grooves or a section other than C, send us the drive data: driving pulley diameter, driven pulley diameter, motor power, revolutions per minute and center distance. With that, an equivalent pulley or a nearby size within the same line can be evaluated. We can also verify the bore diameter and the keyway before manufacturing.

MR Accesorios Industriales manufactures this pulley and other drive parts in its workshops. If you already have the part number POLEA 360 4C, send it by WhatsApp along with the quantity and the shaft data, and we will send you the quote. If you are not sure about the part number, send us a photo of the old pulley or the measurements taken with a caliper and we will check it.
