The POLEA 330 2C pulley is an industrial pulley with a 330 mm diameter and 2 grooves for section C belts. It is used to transmit power between shafts in V-belt drive equipment, where two parallel drive lines are needed. It is in-house manufactured, EMMAR Accesorios Industriales brand, which allows machining and balancing to be controlled. It is mounted on shafts with a keyway and aligned with the drive pulley to prevent uneven wear.

The POLEA 330 2C is identified by three specific data points: 330 mm size, 2 grooves and section C. That combination defines the approximate pitch diameter and the number of belts it can hold. Section C corresponds to V-belts with a wide profile, suitable for transmitting medium and high power at moderate drive ratios. The machined groove guides the belt and maintains contact on the flanks, which is where the force is transmitted.

It is used in belt drive equipment: industrial fans, compressors, centrifugal pumps, conveyor belts and process machines. It also appears in gear reducers and multipliers where an electric motor needs to be coupled to a working shaft at a fixed ratio. In all those cases, the 2-groove pulley allows the load to be distributed between two belts, which reduces the tension on each one and improves drive continuity.

To mount it, check that the shaft has a diameter and keyway compatible with the pulley bore, and that the key fits without play. Align the pulleys with a straightedge or an alignment laser: angular or parallel misalignment accelerates belt and groove wear. Tension the belts according to the equipment manual and check the tension after the first hours of operation. If the pulley runs at high speeds, balancing should be checked.

If you need a pulley with a different number of grooves, a different diameter or a different section, a nearby size within the same manufacturing line can be evaluated. To do so, send the part number POLEA 330 2C or the drawing or sample with the bore, keyway and number of groove measurements. With that data, it is determined whether a pulley from the series is suitable or a custom development is better.
