The 150 4C pulley is a four-groove, section C V-belt pulley with a 150 mm diameter. It transmits power from a motor to a driven shaft, splitting the load across four belts to increase torque capacity and balance. Manufactured in-house under the EMMAR brand, it is built for continuous-duty equipment that needs a sturdy, well-balanced pulley with accurately cut grooves for proper belt seating and wear.

This pulley measures 150 mm in diameter and has four grooves for section C belts. Section C is the wide-profile V-belt used when a significant amount of power must be transferred with a limited number of belts. Distributing the drive across four belts reduces the tension on each one, which helps the entire assembly last longer. The 150 mm diameter, when paired with the motor pulley, sets the transmission ratio: a larger driven pulley lowers the speed and raises the torque. The grooves are machined so the belt contacts the flanks rather than the bottom.

Typical uses include heavy transmission equipment such as screw compressors, high-flow industrial fans, mills, mixers, conveyor belts, and continuous production machines. In these settings, the pulley needs enough mass to damp vibration and the grooves must stay aligned so all four belts pull evenly. It also serves as a replacement for worn pulleys where the grooves have become deformed or polished, causing the belt to slip or come off. Because it is section C, it works with belts of that profile, which are commonly available from transmission suppliers.

When mounting, first confirm the shaft diameter and keyway are correct. The pulley is secured with a key and set screw or with a taper bushing, depending on the setup. Align the motor and driven pulleys using a straightedge or laser; even a small misalignment can wear the belts on one side and put extra load on the equipment bearings. Tension the belts according to the belt manufacturer's instructions, and no tighter than needed. If replacing a pulley, verify that the section, number of grooves, and outside diameter match the old one so the transmission ratio stays the same.

If you need a different number of grooves, another diameter, or a different section, it can be manufactured. To request an equivalent, send the part number POLEA 150 4C or the original pulley data: outside diameter, number of grooves, belt section, and shaft diameter with keyway. With that information we can propose a similar pulley or make it to order. We can also quote the complete assembly with bushing, key, and screws if needed.

To get a quote for this pulley or ask about a special size, contact us by WhatsApp or email and include the part number POLEA 150 4C. We will reply with the manufacturing options. If you are unsure about the section or number of grooves, send a photo of the old pulley or the shaft measurements and we will help you identify the correct part.
