The 330 6B pulley is a section B V-belt drive pulley, with a 330 mm diameter and 6 grooves. It is used to transmit power between parallel shafts in industrial equipment, where the load needs to be distributed among several belts and a stable transmission ratio maintained. It is in-house manufactured, EMMAR Accesorios Industriales brand, which allows the machining and balancing to be adjusted according to the application.

This item is a pulley with a 330 mm diameter, 6 grooves and section B. The designation POLEA 330 6B summarizes those three variables: outside diameter, number of grooves and belt profile. Section B corresponds to classic V-belts of profile B, and the 6 grooves allow up to six belts to be mounted in parallel on the same body. The machining of the grooves and the balancing are controlled so that the assembly rotates without vibration at the usual working speeds.

It is used in power transmissions of equipment such as compressors, fans, centrifugal pumps, mills, conveyor belts and process machines. It also appears in reducers and multipliers where a fixed ratio between two shafts is needed. Because it has 6 grooves, it is suitable for medium and high powers within section B, and it allows continued operation with a margin if one belt wears before the others, which is common in installations with many hours of running.

To select it, take into account the pitch diameter, the number of grooves, the belt section and the type of keyway or bushing the shaft needs. Check the alignment between pulleys, the belt tension and the condition of the grooves before mounting. If the pulley is going to work at high speed, it is advisable to check the balancing. Lubrication does not apply to the pulley, but care of the shaft bearings and cleaning of the grooves does.

If you need another number of grooves or a pulley for a different section, send us the part number POLEA 330 6B or the equipment data: diameter, grooves, section and shaft type. With that we look for an equivalent or manufacture the pulley to measure. We can also quote the assembly with bushings, keys and belts so that you receive everything together and avoid incompatibilities during assembly.
