The 350 6C pulley is a V-belt drive pulley, section C, 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 runs many hours per 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 considerable power must be transmitted with few belts. The 6 grooves allow the load to be distributed among six belts, so each one works under 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 at 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 plant pulley, not for a specific piece of equipment: if the shaft and belt match, it can replace a worn pulley or be used to build 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 secured with a key and screw or with a taper bushing, depending on how the bore is machined. Before installing 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 wear down. Tension the belts according to the equipment manual and recheck the tension after the first hours of operation.

If you need the same pulley but with a different diameter, a different 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 from another brand and want to replace it. For that, send us the full part number, the number of grooves, the section and the outside diameter, and if possible, a photo of the old pulley with the shaft visible. With that data we'll tell you whether a standard size or a special manufacturing is advisable.

MR Accesorios Industriales manufactures this pulley locally, with control of diameter, grooves and balancing.
