The 650 mm industrial pulley with 4 grooves, section C, is a power transmission component mounted on a machine shaft to receive or deliver motion through V-belts. It is used in equipment that needs to distribute rotation across several belts, such as fans, compressors, pumps and conveyors. It is an in-house manufactured part, EMMAR Accesorios Industriales brand, designed to integrate into demanding transmission systems.

This item is a pulley with a 650 mm diameter, 4 grooves and section C. The designation POLEA 650 4C summarizes those three variables: the outer diameter, the number of grooves and the belt profile it accepts. Section C corresponds to a medium-sized V-belt profile, suitable for transmitting moderate to high power depending on the diameter and the number of grooves. Having four grooves allows the load to be distributed across four belts, which reduces the tension on each one and improves drive continuity.

Typical applications of a pulley of this size and configuration appear in continuous process equipment: high-flow industrial fans, screw compressors, large centrifugal pumps, belt conveyors and mixers. It is also found in machine tools and in transmission systems where a stable speed ratio and low maintenance are required. Because it is in-house manufactured, MR can adjust the machining of the bore and the keyway according to the shaft of the equipment it is intended for.

To correctly select a 650 mm pulley with 4 grooves, section C, you must verify the shaft diameter, the type of fixing (keyway, taper bushing or set screw), the center distance and the desired transmission ratio. It is also advisable to check the alignment between pulleys and the belt tension, because misalignment accelerates wear on the grooves and the belts. The number of grooves should be chosen based on the power to be transmitted and the diameter of the driving pulley.

If you need a nearby size, a different number of grooves or a pulley for a different shaft, the most practical thing is to send the part number POLEA 650 4C by WhatsApp along with the equipment data: shaft diameter, belt section, number of grooves and center distance. With that data, MR Accesorios Industriales can offer you an alternative from its in-house manufacturing line or tell you whether a custom pulley is advisable. You can also ask about the machining of the bore and the keyway.

MR Accesorios Industriales manufactures this pulley at its plant and sells it directly, without intermediaries. If your equipment runs with section C belt transmission and you need to replace a 650 mm pulley with four grooves, write to us on WhatsApp with the part number POLEA 650 4C and we will send you the quote. We can also advise you on mounting and alignment so that the transmission runs evenly and durably.
