The 650 3C pulley is a section C V-belt drive pulley, with a 650 mm diameter and three grooves. It is used to drive large shafts in industrial equipment, where power must be transmitted with several belts in parallel. Since it is in-house manufacturing, EMMAR brand, the machining can be adjusted to the size and the type of bushing the equipment needs. It is quoted by WhatsApp indicating the part number.

This item is a pulley with a 650 mm diameter, 3 grooves and section C. The designation POLEA 650 3C summarizes those three variables: size, number of grooves and belt profile. Section C corresponds to wide-profile V-belts, the ones used when more power must be transmitted than with smaller sections. The three grooves allow mounting three belts in parallel on the same disc, which distributes the load among them and reduces the stress on each one.

Typical applications for a pulley of this size are in low-speed, high-torque equipment: mills, mixers, screens, conveyor belts, high-flow exhausters and continuous process machines. It is also used in gear reducers and in drives where the driving or driven shaft has a considerable diameter. In all those cases, the pulley is chosen by the outside diameter, the number of grooves and the type of bushing or bore that goes on the shaft.

To mount a 650 mm pulley with three grooves, it is advisable to verify the alignment between pulleys, the belt tension and the condition of the grooves. A misaligned pulley or one with worn grooves accelerates belt wear and generates vibration. You must also check that the bushing or the tapered bore matches the shaft diameter and the fastening system. If the equipment works with variable loads, the number of grooves and the section are defined together with the drive calculation.

If you need a pulley with a different number of grooves, another diameter or a different section, you can request a nearby size or an equivalent. For that, send the part number POLEA 650 3C or the equipment data: pulley diameter, belt section, number of grooves and shaft size. With that data we evaluate whether an in-house manufactured pulley with the appropriate machining is better or if there is an alternative within the power transmission line.

MR Accesorios Industriales manufactures this pulley and other transmission parts in its workshops. If you have doubts about the designation, the number of grooves or the type of bushing, write to us on WhatsApp with the part number POLEA 650 3C and we will help you confirm the part before quoting.
