The POLEA 300 4B pulley is a power transmission component manufactured by EMMAR Accesorios Industriales. It is a pulley with a 300 mm diameter, with 4 grooves for section B belts. Its function is to transmit motion from a drive shaft to a driven shaft, allowing speed to be regulated by means of the diameter ratio. It is suitable for industrial applications that require transmitting torque with one or several V-belts.

This item is a pulley with a 300 mm diameter, with 4 grooves and section B. The designation POLEA 300 4B summarizes those characteristics: the number 300 indicates the size in millimeters and 4B the number of grooves and the belt section. It is manufactured by EMMAR, which guarantees control over machining and material quality. It is used with section B V-belts, which are common in industrial drives.

Typical applications include machine tools, compressors, fans, centrifugal pumps, conveyors and transmission equipment in general. Having four grooves allows the load to be distributed among several belts, which is useful when high power needs to be transmitted or when redundancy is sought in case a belt breaks. It is also used in systems where speed needs to be adjusted by varying the pulley ratio.

For mounting, check that the shaft and keyway are clean and free of burrs. The pulley must be perfectly aligned with the drive pulley to avoid irregular belt wear and vibrations. Belt tension must be adequate: too low causes slipping and too high overloads the bearings. When selecting, take into account the power to be transmitted, the shaft rpm and the minimum recommended diameter so as not to compromise strength.

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 one. For that, send us the part number POLEA 300 4B or the data of the original pulley: diameter, grooves, section and bore type (cylindrical or tapered). We can also advise you if you have doubts about the right transmission ratio for your equipment.

At MR Accesorios Industriales we manufacture pulleys and other transmission components. If this item matches what you need, write to us by WhatsApp with the part number POLEA 300 4B and we'll send you the quote. We can also help you find the pulley that replaces the one you are using, even if you don't have the part number at hand.

Frequently Asked Questions

What does POLEA 300 4B mean?
The 300 indicates the outside diameter in millimeters, 4 the number of grooves and B the V-belt section. It is a pulley to mount on shafts and transmit motion by means of section B belts.
Can I use belts of another section on this pulley?
No, the grooves are machined for section B belts. Using another section can damage the belt or the pulley. If you need another section, ask us about an equivalent pulley.
How do I request a pulley with other dimensions?
Write to us by WhatsApp with the part number POLEA 300 4B and the dimensions you need: diameter, number of grooves, section and bore type. We'll quote you a custom pulley or a similar alternative.
