The 450 3C pulley is a power transmission pulley manufactured by EMMAR, with 450 mm diameter and 3 grooves for section C belts. It is used in machines that need to transmit torque with several belts in parallel, such as mills, mixers, compressors and process equipment. Being in-house manufacturing, MR controls the groove machining and balancing, which results in even operation and less belt wear.

This pulley has 450 mm diameter, 3 grooves and section C. It is a cast iron or machined steel pulley, with grooves turned according to the section C standard so that the belt seats correctly. The outside diameter and the number of grooves define the transmission ratio and the number of belts you can mount. Being in-house manufacturing, EMMAR brand, the bore, keyway and fixing system can be machined according to your machine's shaft.

It is used in equipment that requires transmitting power with section C belts: mills, mixers, compressors, pumps, fans and conveyors. Also in agricultural and industrial machines where a large diameter pulley with several grooves is needed to distribute the load. It is common to find it on the input shaft of gearboxes or on the motor, depending on the transmission design.

To mount it, verify that the bore and keyway match the shaft, and that the pulley is aligned with the driving pulley to avoid uneven belt wear. If the pulley will work at high revolutions, it is advisable to balance it. When selecting, take into account the power to transmit, the shaft speed and the number of belts. Section C admits a range of power per belt; with 3 grooves you can cover more load or use smaller section belts if the calculation allows it.

If you need a pulley with another size, another number of grooves or a different section, it can be custom manufactured. To request an equivalent or a nearby size, send us the original pulley part number, the number of grooves, the section and the outside diameter. A photo of the pulley and the type of belt it uses also helps. With that data we quote the pulley that best suits your machine.
