The pulley 350 6C is a section C V-belt drive pulley, with a 350 mm diameter and 6 grooves. It is used to drive shafts from a motor, distributing power among several belts to transmit more torque without slipping. It is an in-house manufactured part, EMMAR Accesorios Industriales brand, designed for equipment that works many hours a day and where the pulley must be well balanced and with aligned grooves.

This pulley has a 350 mm diameter, 6 grooves and section C. Section C corresponds to wide-profile V-belts, the ones used when a fair amount of power must be transmitted with few belts. The 6 grooves allow the load to be distributed among six belts, so each one works with less tension and the assembly lasts longer. The 350 mm diameter defines the transmission ratio when combined with the motor pulley: the larger the diameter, the fewer revolutions on the driven shaft and the more torque available.

It is used in screw compressors, mills, mixers, screens, large centrifugal pumps, industrial fans and continuous process machines. Also in lifting and conveying equipment, such as belts and bucket elevators, where motion must be transmitted from a gearbox or an electric motor. It is a general-purpose pulley in the plant, not for a specific piece of equipment: if the shaft and belt match, it serves to replace a worn pulley or to assemble a new drive.

To mount it, check that the shaft diameter matches the pulley bore and that the keyway is in good condition. The pulley is fastened with a key and screw or with a taper bushing, depending on how the bore is machined. Before putting on the belts, align the pulleys with a straightedge or a laser: a misalignment of a few millimeters causes the belts to wear on one side and the grooves to be eaten away. Tension the belts according to the equipment manual and check the tension again after the first hours of work.

If you need the same pulley but with another diameter, another number of grooves or for another type of belt, it can be manufactured to measure. We can also evaluate an equivalent if you have a pulley of another brand and want to replace it. For that, send us the full code, the number of grooves, the section and the outside diameter, and if you can, a photo of the old pulley with the shaft visible. With that data we will tell you whether a standard size or a special manufacturing is better.

MR Accesorios Industriales manufactures this pulley locally, with control of diameter, grooves and balancing. If you need it for equipment that is stopped, send the code PULLEY 350 6C by WhatsApp and we will send you the quote. You can also ask about other section C pulleys, taper bushings, V-belts and mounting tools. We serve industries, workshops and maintenance throughout the country.
