The 330 2B pulley is a V-belt drive pulley, manufactured by MR Accesorios Industriales. It has a 330 mm diameter, two grooves and section B. It is used to transmit power between parallel shafts in industrial machines and installations, where a defined transmission ratio and good belt grip are needed. Because it is in-house manufactured, you can ask about machining and balancing variants according to the application.

This item is a pulley with a 330 mm diameter, 2 grooves and section B. The designation POLEA 330 2B summarizes those three characteristics: the 330 mm outside diameter, the number of grooves (2) and the belt section it houses, B. Section B corresponds to classic V-belts of profile B, and the two grooves allow mounting two belts in parallel on the same pulley. The machining of the bore, the keyway and the balancing are defined according to the shaft and the working revolutions.

It is used in belt transmissions of machine tools, compressors, fans, pumps, conveyor belts and process equipment. It also appears in reducers and multipliers where a driving or driven pulley of medium diameter is needed. Having two grooves, it is common in drives that require greater transmission capacity or a certain redundancy: if one belt fails, the other keeps transmitting until it is replaced.

To select it, take into account the pitch diameter required by the transmission ratio, the belt section (B in this case) and the number of grooves. Verify that the bore and the keyway match the shaft, and that the balancing is adequate for the rotation speed. In transmissions with more than one belt, it is advisable that all work with the same tension and that the pulleys are aligned to avoid uneven wear.

If you need an equivalent pulley or a nearby size, send us the part number POLEA 330 2B or the diameter, number of grooves and section you are looking for. We can also evaluate bore, keyway or material variants. As it is in-house manufacturing, EMMAR brand, we have flexibility to adapt the machining to your shaft and your application.
