The 320 6B pulley is a V-belt drive pulley, manufactured by EMMAR Accesorios Industriales. It has a 320 mm diameter, 6 grooves and section B, which makes it suitable for transmitting power in equipment that requires several belts in parallel. It is used in fans, compressors, pumps and production machines that work with moderate to high load regimes. Because it is in-house manufactured, MR controls the machining of the grooves and the balancing, two key factors for the belts to last and the equipment not to vibrate.

This item is a pulley with a 320 mm diameter, 6 grooves and section B. Section B corresponds to classic profile V-belts, and the 6 grooves allow mounting up to six belts in parallel on the same pulley. The 320 mm diameter defines the transmission ratio when combined with another pulley in the same system. The designation POLEA 320 6B summarizes those three data points: size, number of grooves and section. It is a machined cast iron part, with ground grooves so that the belt support is uniform throughout its entire length.

The typical applications of a pulley of this type are in driving industrial fans, screw compressors, centrifugal pumps and transmission lines with medium-power electric motors. It is also used in production machines where the load needs to be distributed among several belts so as not to overload a single one. In all those cases, the pulley is mounted on the shaft of the driven equipment or the motor, and works together with a driving or driven pulley of a different diameter to achieve the working speed.

To select and mount this pulley, take into account the belt section: it must be B, not A or C. Verify that the 320 mm diameter is compatible with the transmission ratio you need and with the space available on the machine. The 6 grooves require that the driving pulley has the same number or a compatible one, and that all belts are changed together so they work with the same tension. Before mounting, check that the shaft has no burrs and that the pulley fits with the correct fit; afterwards, align the pulleys with a straightedge or a laser to avoid uneven wear.

If you need an equivalent pulley or a nearby size, the most practical thing is to send us the part number POLEA 320 6B or the data of the original pulley: diameter, number of grooves and section. With that we can verify whether we have an in-house manufactured pulley with those characteristics or whether it is better to adapt an existing one. We can also advise you if the space does not allow 320 mm and a smaller or larger diameter must be found, always respecting section B and the number of grooves required by your transmission.

MR Accesorios Industriales manufactures this pulley at its plant and sells it directly. If you want to request a quote or ask about a similar size, send the part number via WhatsApp and we will reply with the technical data. We can also advise you on the mounting, alignment and tension of the belts so that the system works without vibrations or premature wear.
