The 280 6B pulley is a B-section V-belt drive pulley, with a 280 mm diameter and 6 grooves. It is used to transmit power between parallel shafts in industrial equipment, allowing speed to be adjusted through the ratio of diameters. Manufactured by MR, it is designed to be mounted on shafts with a keyway and fastened with set screws or taper bushings as applicable. It is a key part in machines that require reliable transmission and low maintenance.

This pulley has a 280 mm diameter, 6 grooves and B section. The designation POLEA 280 6B summarizes those three variables: the outer diameter, the number of grooves and the belt profile it accepts. Section B corresponds to classic V-belts of wide profile, suitable for transmitting medium and high power. Being of in-house manufacturing, EMMAR brand, the critical dimensions and balancing are controlled for stable operation.

It is used in compressors, industrial fans, centrifugal pumps, mills, mixers and transmission lines in general. It also appears in machine tools and process equipment where the speed of the driven shaft needs to be varied. Having 6 grooves, it allows the load to be distributed among several belts, which reduces the stress on each one and provides redundancy: if one fails, the remaining ones keep transmitting until it is replaced.

To select correctly, take into account the pitch diameter, the power to be transmitted, the RPM of the drive shaft and the type of load. Verify that the keyway and the shaft diameter match the pulley bore. Alignment between pulleys is essential to avoid irregular belt wear and vibrations. It is recommended to use belts of the same brand and batch, and to tension them according to the belt manufacturer's instructions.

If you need a pulley with another 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 280 6B or the data of the original pulley: diameter, grooves, section and bore diameter. We can also advise you if you have doubts about the transmission ratio or the type of bushing. Write to us on WhatsApp and we will reply with the alternative that best suits your equipment.
