The 500 6B is a V-belt pulley measuring 500 mm across and featuring six grooves cut for section B belts. Drives that split power among multiple belts, such as mills, mixers, compressors and conveyors, commonly use this configuration to link parallel shafts. Because it is manufactured in-house under the EMMAR brand, the bore, keyway and balancing can be machined to match the shaft where it will sit. For a replacement or a new build, send the part number along with your shaft dimensions.

Key figures: outside diameter 500 mm, groove count 6, belt section B. Section B is a traditional narrow V-belt profile. Six grooves of this size allow the pulley to carry more torque than one with fewer grooves at the same diameter. A 500 mm diameter produces a low drive ratio when paired with a small driver pulley and a high tangential speed, so balancing and alignment checks before installation are recommended. The pulley arrives without a finished bore, ready for machining to your shaft.

Typical applications include hammer mills, horizontal mixers, screw compressors, vibrating screens, belt conveyors and pumping equipment, where a shaft must turn slowly with solid torque. You will also find it on older machines when a worn or cracked pulley needs replacing. In those cases, keeping the diameter, groove count and belt section unchanged is critical: altering any of these shifts the equipment speed and the power it can deliver.

When selecting the pulley, consider shaft diameter, bore length, keyway type and balancing. Fast-turning shafts benefit from dynamic balancing to reduce vibration. Also verify center distance and belt length, since a different pulley diameter may call for a different belt. Pulleys must be aligned square to each other so belts do not come off or wear on one side. Under heavy load, use all grooves with belts of equal length.

If you need a different diameter or fewer grooves, we can manufacture it. Send the current part number, outside diameter, groove count and belt section. Shaft diameter and keyway type are also helpful. With that information we will quote an equivalent pulley or an intermediate size. If the section is unknown, measure the belt width or send a photo of the old pulley and we will identify it.
