The 120 6B is a section B V-belt pulley built in-house under the EMMAR brand. Its 120 mm diameter and six grooves let you run multiple belt strands side by side on one shaft, which suits drives where the load is shared across grooves and the ratio needs to stay steady. Fans, compressors, pumps and conveyors are common homes for this size.
Read the designation POLEA 120 6B as three pieces of information: 120 is the diameter in millimeters, 6 is the groove count, and B is the V-belt profile. Six grooves means up to six section B belts can be mounted on the same pulley. Because MR machines this item itself, groove geometry and balancing stay under our own shop control.
Six-groove section B pulleys turn up in drives that move a fair amount of power through a small diameter: centrifugal fans, screw compressors, centrifugal pumps, mixers and belt conveyors, plus machine tools and process equipment already set up for section B belts. With several grooves in play, a single failed belt does not stop the equipment; the remaining belts carry the drive until the next scheduled shutdown, which plant crews tend to appreciate.
Before mounting, confirm the bore and keyway match the shaft and that the belt section is B. Line up the pulleys with a straightedge or laser, since even a few degrees of misalignment cuts belt life and loads the bearings. Set tension per the belt maker's manual rather than by feel. When replacing an existing pulley, note the outside diameter, groove count and bore diameter before you order.
For an equivalent, send the full part number of the pulley in service, a photo, and if you have them the shaft diameter and groove count. That is usually enough to tell whether something in our line substitutes for it or whether building to size makes more sense. Knowing which belt the equipment runs also helps, since the profile drives the selection.

Frequently asked questions
- What does the 6B in the designation mean?
- The 6 is the number of grooves and the B is the V-belt section, so the pulley accepts up to six section B belts running in parallel on one shaft. The 120 mm diameter rounds out the designation.
- Can I run belts of a different section on this pulley?
- It is not recommended. The grooves are cut for the B profile, and a belt of another section will not seat correctly, which leads to slipping, faster wear and less power transmitted. If you need a different section, ask us about alternatives in our line.
- How do I order a pulley that matches the one I have installed?
- Send the part number of the current pulley, a photo, and the shaft data: diameter, keyway and groove count. From that we can judge whether one of our pulleys replaces it or whether making it to size is the better route.
