The 90 3C pulley is a power transmission pulley of in-house manufacturing, EMMAR brand, with a 90 mm diameter, 3 grooves and C section. It is used to transmit motion between shafts by means of V-belts, in machines and equipment that need a reliable transmission ratio with little maintenance. Being a three-groove pulley, it multiplies torque capacity compared with a single-groove pulley. MR Accesorios Industriales manufactures and sells it.

This pulley measures 90 mm, with 3 grooves and C section. C section corresponds to wide-profile V-belts, suitable for transmitting medium and high power. The three grooves distribute the load among three belts, which increases transmission capacity and provides redundancy: if one belt fails, the other two keep pulling. The 90 mm diameter defines the transmission ratio when combined with the driven pulley. It is an in-house manufactured part, EMMAR brand, designed to last in continuous service.

It is used in belt drive equipment: compressors, fans, pumps, mills, conveyor belts, mixers and machine tools. Also in the field, in agricultural implements and in process plants. It is common in installations where the driven shaft speed needs to be varied by changing the pulley diameter. Being C section with three grooves, it is common in applications requiring smooth running and vibration absorption, something the V-belt provides by itself.

To mount it, check that the shaft and keyway are clean and free of burrs, and that the pulley fits without forcing. Align the pulleys with a straightedge or laser to avoid uneven wear of belts and grooves. Belt tension must be the one recommended by the belt manufacturer; if they are loose, they slip and wear; if they are too tight, they stress the shaft bearings. When selecting, take into account the power to be transmitted, the rpm of the drive shaft and the diameter of the driven pulley to calculate the ratio and the peripheral speed.

If you need an equivalent pulley, send us the full part number, the section, the number of grooves and the diameter. It also helps if you tell us the shaft diameter and the type of keyway. With that data we propose the pulley with similar characteristics that corresponds or we manufacture it. We work with standard sizes and also with custom manufacturing within our power transmission line.

To request a quote for this pulley or ask about another size, send the part number POLEA 90 3C by WhatsApp to MR Accesorios Industriales. We reply with the alternatives that best fit your application. If you have doubts about the section or the number of grooves, we can also advise you so that you choose the right pulley and do not oversize the system.

Frequently Asked Questions

What does it mean that it is C section?
C section is a V-belt profile wider than sections A or B. It is used to transmit more power per groove. This pulley has three C-section grooves, so it accepts three belts of that profile.
How do I know if a 90 mm pulley works for me?
It depends on the motor rpm and the speed you need on the driven shaft. With the diameter of the drive pulley and the driven pulley, the transmission ratio is calculated. Send us that data and we'll help you verify it.
Can I order a pulley with a different number of grooves?
Yes. We manufacture C-section pulleys with different numbers of grooves and diameters. Tell us the size, the grooves and the shaft diameter, and we'll quote the option you need.
