The EMMAR 350 6C is a six-groove V-belt pulley built to section C. It measures 350 mm in diameter and is used to take drive from a motor or gearbox and pass it to a driven shaft. Because the load is shared across six belts, no single belt carries the full tension. The pulley is manufactured in-house, so diameter, groove form and balance are controlled at the source.

Reading the designation is straightforward: 350 is the diameter in millimeters, 6 is the number of grooves and C is the belt section. Section C is the wide-profile V-belt family, chosen when a fair amount of power has to move through a small number of belts. Diameter also sets the ratio against the motor pulley, so a larger driven pulley means lower shaft speed and more torque at the driven end.

Typical installations include screw compressors, mills, mixers, screens, large centrifugal pumps, industrial fans and continuous process lines. Lifting and conveying equipment such as belt conveyors and bucket elevators also use this size, whether the input comes from an electric motor or a gearbox. It is a general plant pulley rather than a part tied to one machine, so it can replace a worn unit or go into a new drive as long as shaft and belt match.

During mounting, confirm the bore matches the shaft and inspect the keyway for wear. Depending on how the bore is machined, the pulley is held by a key and screw or by a taper bushing. Align the pulleys with a straightedge or laser before the belts go on, since even a few millimeters of offset will wear one side of the belts and erode the grooves. Set tension per the equipment manual and check it again after the first hours of running.

Other diameters, groove counts or belt sections can be produced to order, and an equivalent can be reviewed if you are replacing a pulley from another brand. Send the complete part number, number of grooves, section and outside diameter, plus a photo of the old pulley showing the shaft if you have one. With that information we can say whether a standard size fits or a special build makes more sense.
