The pulley 280 6B is a V-belt transmission pulley, section B, with a diameter of 280 mm and 6 grooves. It is used to transmit power between parallel shafts in industrial equipment, allowing speed adjustment through the diameter ratio. Manufactured by MR, it is designed to be mounted on keyed shafts and secured with set screws or taper bushings as applicable. It is a key component in machines that require reliable transmission and low maintenance.
This pulley has a diameter of 280 mm, 6 grooves and section B. The designation PULLEY 280 6B summarizes these three variables: the outside diameter, the number of grooves and the belt profile it accepts. Section B corresponds to classic V-belts with a wide profile, suitable for transmitting medium and high power. As an in-house manufactured product, EMMAR brand, 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. With 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 continue transmitting until it is replaced.
For correct selection, 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 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 a different number of grooves, another diameter or a different section, we can manufacture it or find an equivalent. To do so, send us the code PULLEY 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 via WhatsApp and we will respond with the alternative that best suits your equipment.

Frequently Asked Questions
- What does PULLEY 280 6B mean?
- The number 280 indicates the diameter in millimeters, the 6 the number of grooves and the letter B the V-belt section it accepts. It is a common nomenclature for identifying transmission pulleys.
- Can I use belts of another section on this pulley?
- No, the grooves are machined for section B. Using a belt of another section can damage the pulley and the belt, and affect the transmission. Always verify that the belt is section B.
- How do I request a pulley with other dimensions?
- Send via WhatsApp the current code or the data you have: diameter, number of grooves, section and bore diameter. With that we will quote a custom pulley or offer you the closest one.
