The 330 3C pulley is a V-belt drive pulley, section C, with a 330 mm diameter and 3 grooves. It is used to drive shafts from a motor, reducing or increasing speed according to the combined diameters. It is in-house manufactured, EMMAR brand, which allows machining, balancing and keyway to be adjusted to what each piece of equipment requires. If you need to replace a worn pulley or build a new drive, this size covers air flow, pumps and medium-sized mills.

This item is a pulley with a 330 mm diameter, 3 grooves and section C. The designation POLEA 330 3C summarizes those three data points: the 330 mm outside diameter, the number of grooves (3) and the belt section it holds, C. The grooves are machined so that the V-belt seats at the correct angle and does not slip or wear on the side. It is in-house manufactured, EMMAR brand, so the machining of the bore, the keyway and the balancing are done according to what the shaft where it is mounted requires.

It is used in belt drives of equipment that move medium loads: industrial fans and exhausters, centrifugal pumps, screw compressors, mills, mixers and conveyor belts. It also appears in agricultural machinery and test benches. With three section C grooves, high power can be transmitted distributed among the belts, and if one breaks the others keep pulling. It is a general-purpose pulley, not an extreme-precision one, and that is why it is found in process plants, workshops and water treatment plants.

To choose it correctly, three things must be considered: the pitch diameter required by the drive ratio, the number of grooves according to the power to be transmitted and the belt section already used by the machine. The shaft diameter and keyway length also matter, because the bore depends on them. During mounting, check that the pulley fits with the proper fit and not by hammering, that the key fits without play and that alignment with the drive pulley is square: a misalignment of a few degrees eats belts and bearings. After mounting, check the tension and check it again a few hours after running.

If you cannot find the exact size, an equivalent pulley or a nearby size can be requested. To do so, it is best to send the diameter, the number of grooves, the belt section and the shaft diameter with the keyway length. With that data, it is determined whether there is a pulley from the same family that works or whether it is better to manufacture it to measure. Pulleys of other sections and numbers of grooves can also be requested within the power transmission line. The more complete the shaft and belt information, the faster it is resolved.

If you already have the part number POLEA 330 3C, send it by WhatsApp to MR Accesorios Industriales and we will send you the quote. If what you need is a similar pulley, write anyway: with the shaft and belt data, the alternative is found. MR Accesorios Industriales manufactures split plummer block housings, ANSI chains and pulleys, and sells bearings, seals, bushings and lubricants to complete the drive.
