The 330 3B pulley is a V-belt drive pulley, manufactured by EMMAR Accesorios Industriales. It has a 330 mm diameter, 3 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 where speed adjustment and reliability are key. As it is in-house manufactured, you can inquire about machining and balancing variants according to your application.

This pulley has a 330 mm diameter, 3 grooves and section B. Section B corresponds to classic profile V-belts, and the three grooves allow the load to be distributed among several belts, which reduces the stress on each one and improves drive continuity. The 330 mm diameter defines the transmission ratio when combined with the motor pulley. It is a cast iron or machined steel part, depending on the use, and is mounted on shafts with keyways. The designation POLEA 330 3B summarizes those three variables: diameter, number of grooves and section.

Typical applications are industrial ventilation equipment, screw and piston compressors, centrifugal pumps, mixers, conveyor belts and machine tools. In all these cases the pulley receives the movement from the motor and transmits it to the machine through section B belts. It is also used in installations where the final speed needs to be corrected without changing the motor, because the 330 mm diameter allows moderate transmission ratios to be obtained. It is a frequently replaced part in plants that work with several belt drives.

To correctly select this pulley, take into account the shaft diameter, the type of keyway and the fastening system (set screw, taper bushing or plate). Verify that the belt section is B and that the number of grooves matches the number of belts you are going to mount. The 330 mm diameter must be compatible with the available space and the permissible peripheral speed. During assembly, align the pulleys precisely and check belt tension to avoid irregular wear and vibrations.

If you need a pulley with a different number of grooves, another diameter or a different section, we can manufacture it or find an equivalent. For that, send us the part number POLEA 330 3B or the data of the original pulley: diameter, grooves, section, shaft diameter and type of fastening. We can also quote a nearby size if yours is not listed. The more data you provide, the faster we will respond with the option that best suits your equipment.
