For drives that call for a 420 mm diameter, two-groove, section B V-belt pulley, the EMMAR 420 2B is a direct option. It handles power transfer between parallel shafts where the ratio is fixed and belt grip matters. Since EMMAR produces it in-house, the bore and keyway can be machined to match your shaft. Send the part number POLEA 420 2B by WhatsApp or email and the team will quote it.

Reading the code: 420 is the diameter in millimeters, 2B means two grooves for section B belts. Section B is the V-belt profile used in medium-power industrial drives. Running two belts side by side raises the transmission capacity without a larger diameter, and it also spreads the load so each belt wears less. The body is cast iron or steel depending on the application, and the bore is machined with the keyway for the shaft it will sit on. The designation POLEA 420 2B identifies this exact size and configuration.

Typical applications include compressors, centrifugal pumps, fans, conveyor belts, mixers and mills, as well as agricultural implements and irrigation equipment. In these machines the pulley changes speed between a motor and a driven machine. A two-groove unit is common where extra torque is needed or where a degree of redundancy is wanted.

When selecting a pulley like this, check the pitch diameter, groove count, belt section and shaft diameter, plus the center distance and the transmission ratio you need. At assembly, align the pulley with the drive pulley, set the correct belt tension and confirm the keyway fits without play. If the pulley mounts on a shaft with a bearing, check for eccentricity.

If you need an equivalent, send the part number POLEA 420 2B or the equipment data: diameter, grooves, section and shaft diameter. The team can propose a similar in-house manufactured pulley or machine one to size, and can also advise on the belt, bushings or supports for the installation.
