The EMMAR 300 6B is a V-belt pulley with a 300 mm diameter, six grooves, and B section. Because EMMAR produces these pulleys in-house, the machining and quality control stay under our supervision. This pulley suits drives that need multiple B-section belts working side by side, such as industrial fans, compressors, and process equipment.

The code 300 6B tells you the essentials: 300 mm diameter, six grooves, B section. B section is a classic V-belt profile, so the pulley only accepts B-section belts. With six grooves, you can run up to six belts in parallel on the same pulley. The part is made from cast iron or machined steel, depending on the production method. It comes with the bore and keyway to be defined for your equipment shaft.

You will find a 300 mm six-groove B-section pulley in industrial fans, screw compressors, centrifugal pumps, mills, mixers, and conveyors. Machine tools and process equipment also use it when speed needs to be adjusted and several belts share the load. Its diameter makes it common in setups that call for a moderate transmission ratio and good belt wrap.

When selecting and mounting this pulley, check the shaft diameter, keyway type, and fastening method (set screw, cone, or bushing). Confirm that your belts are B section and that the groove count matches the number of belts you plan to use. Align the pulleys and tension the belts following the belt manufacturer's instructions. If you need balancing, specify the required grade. We can machine a custom bore and keyway.

For an equivalent, send the complete part number of the pulley you are replacing, along with the number of grooves, the section, and the outside diameter. We can also make a pulley with the same performance but a different diameter or groove count. Since EMMAR manufactures in-house, we can adapt the machining to your shaft. Ask about special sizes or pulleys in other sections.
