The EMMAR 280 3A is a V-belt pulley made in-house by MR Industrial Accessories. It measures 280 mm in diameter and has three grooves cut for section A belts. This pulley transfers power between parallel shafts on industrial machinery, and because we manufacture it ourselves, the machining can be adjusted to match your specific application. If you need a three-groove pulley for A-section belts, this size is among the most frequently requested.
The code POLEA 280 3A tells you the essentials: the outer diameter, the number of grooves, and the belt profile. Section A refers to classic V-belts with a 13 mm top width, so the grooves are machined to that profile. The pulley mounts on a shaft and transmits motion through belts.
Typical applications include compressors, fans, pumps, conveyor belts, mixers, and mills — equipment that needs to move power between parallel shafts. Three grooves let you spread the load across three belts, which adds transmission capacity and provides some redundancy if one belt fails. It is also a common choice when you want to lower the tension on each belt or when space limits the pulley diameter.
When selecting this pulley, check the pitch diameter, groove count, and belt section. Confirm that the shaft diameter and keyway match, and that the pulley aligns with the driven pulley to prevent uneven belt wear. In equipment with high vibration or variable loads, it is wise to check balancing and the tightness of the fastening screws.
If you need a similar pulley in another size, with a different number of grooves, or for another belt section, we can manufacture it. Send the code POLEA 280 3A or the details of your original pulley — diameter, grooves, section, and shaft type — and we will quote you by WhatsApp or email. We can also look at a replacement if the pulley you have is no longer available.

Frequently asked questions
- What does section A mean?
- Section A corresponds to classic V-belts with a 13 mm top width. The pulley grooves are machined with that profile so the belt seats correctly. If your belt is another section, such as B or C, you need a pulley with the matching groove.
- Can I order a pulley with a different number of grooves?
- Yes. Since we manufacture in-house, we can make it with 1, 2, 3, or more grooves according to your needs. Send us the data of the original pulley or the equipment and we will quote the variant that fits best.
- How do I know if this pulley replaces the one I have?
- Compare the outer diameter, number of grooves, and belt section. Also check the shaft diameter and keyway. If you are unsure, send us a photo or the data of the old pulley by WhatsApp and we will help you confirm.
