When you need to replace a worn sheave or set up a new belt drive, the EMMAR 320 5B pulley gives you a 320 mm diameter and five grooves for B-section belts. It is made in-house by MR and is intended for industrial power transmission between shafts.

The part number POLEA 320 5B tells you the key details: a 320 mm diameter, five grooves, and a B-section profile. In a B-section V-belt, the belt itself has a top width of 17 mm and a height of 11 mm, but those figures describe the belt, not the pulley. The pulley is produced in steel or cast iron and the grooves are machined to mate correctly with the belt.

With five grooves, the drive can share the load across several belts. That helps when you need to transmit more power or speed without relying on a single belt. The 320 mm size fits medium transmission ratios where peripheral speed and load capacity need to be balanced.

You will find this pulley in belt drives on centrifugal pumps, fans, compressors, conveyors, and process equipment. It also shows up in agricultural implements and in maintenance shops where a worn pulley is being replaced. Before mounting, check that the shaft diameter and keyway match the pulley. Align the pulleys carefully to prevent uneven belt wear and vibration. When selecting a pulley, account for the power to be transmitted, the rotation speed, and how many belts you need.

If your application calls for a different diameter, groove count, or section, MR can manufacture it to order. To request an equivalent, send the part number POLEA 320 5B or your specifications and the team will reply promptly. You can also ask for a special pulley made from a sample or drawing.
