The 100 3C pulley is a V-belt drive pulley, manufactured by EMMAR in section C with three grooves and a 100 mm diameter. It is used to transmit power between parallel shafts in industrial equipment, where a stable transmission ratio and good belt grip are needed. As it is in-house manufactured, dimensions and balancing are controlled so that it works without vibrations at the usual speeds of the line. It is quoted by WhatsApp indicating the part number.

This item is a pulley with a 100 mm diameter, 3 grooves and section C. The POLEA 100 3C designation 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 in relation to their size. The three grooves allow the load to be distributed among three belts, which gives margin to work with only one if necessary, or to increase transmission capacity using all three.

It is used in machines that need to reduce or increase revolutions between a motor and a working shaft: compressors, fans, centrifugal pumps, mixers, conveyor belts and factory equipment. It also appears in field drives, where the motor shaft is not aligned with that of the machine and is solved with pulleys and belts. In those cases, the three-groove pulley is chosen when the torque to be transmitted is not covered by a single section C belt.

To mount it, verify that the shaft diameter matches the pulley bore and that the key fits without play. The pulley must be aligned with the driving pulley: angular or parallel misalignment wears the belts on one side and generates vibration. Tension is adjusted according to the equipment manual or the usual practice for section C belts, without letting them slip or leaving them too tight. If the pulley works at many revolutions, it is advisable to check the balancing before putting it into service.

If you need another size, another number of grooves or a pulley for a different shaft, a variant can be requested. MR manufactures pulleys and bearing housings, so inquiries about a neighboring size or a special development go through the same channel. To do so, send the POLEA 100 3C part number or the designation of the part you are replacing, along with the belt section and the number of grooves you need. With those data the quote is issued.
