The 90 3C pulley is an in-house manufactured power transmission pulley, EMMAR brand, with 90 mm diameter, 3 grooves and section C. It is used to transmit motion between shafts by means of V-belts, in machines and equipment that need a reliable transmission ratio and low maintenance. With three grooves, it multiplies torque capacity compared to a single pulley. MR Accesorios Industriales manufactures and sells it with more than 80 years of experience in the field.

This pulley has a size of 90 mm, 3 grooves and section C. Section C corresponds to wide-profile V-belts, suitable for transmitting medium and high power. The three grooves allow the load to be distributed 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 to find it in installations where the driven shaft speed needs to be varied by changing the pulley diameter. Being section C and three grooves, it is common in applications that require smooth running and vibration absorption, something the V-belt provides by itself.

To install 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 motor shaft and the diameter of the driven pulley to calculate the ratio and the tangential speed.

If you need an equivalent pulley or a nearby size, 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 keyway type. With that data we can verify whether we have a pulley with similar characteristics or whether it is better to manufacture it. We work with standard sizes and also with custom manufacturing within our power transmission line.
