The EMMAR 400 2B pulley is a two-groove, section B V-belt pulley with a 400 mm diameter, manufactured in-house. It is designed to transfer power between shafts in industrial drives, and its two grooves allow you to run two belts in parallel when the load needs to be shared.

The part number POLEA 400 2B tells you the three key details: 400 for the diameter in millimeters, 2 for the number of grooves, and B for the belt cross-section. Because section B defines the groove width and depth, you must pair this pulley with a section B belt. As an in-house manufactured item, it is produced under the same dimensional controls we apply across our transmission line.

You will find this pulley on industrial fans, centrifugal pumps, compressors, conveyors, and machine tools. Running two section B belts is useful when torque is high or when you want a degree of redundancy—if one belt fails, the other keeps the drive running until you can service it. It is also a practical way to adjust an existing speed ratio.

Before mounting, check the shaft diameter and the fastening method (keyway, taper bushing, or set screw, as applicable). Confirm the belt is section B and that the center distance gives you the belt length you need. Align the pulleys with a straightedge or laser to prevent uneven groove and belt wear. Set tension according to the equipment manual: too tight loads the bearings, too loose slips and overheats.

If you are looking for an equivalent, send us the complete part number of the pulley you are replacing, the belt section, and the number of grooves. With that information we can check whether a pulley in our line fits or if a custom build is a better option. Including the shaft diameter and a photo of the assembly helps us quote accurately and avoid back-and-forth.
