The 500 6B pulley is a V-belt drive pulley, with a 500 mm diameter and 6 grooves for section B belts. It is used to drive parallel shafts in equipment that needs to distribute power across several belts, such as mills, mixers, compressors and conveyors. Because it is in-house manufactured, EMMAR brand, the bore, keyway and balancing can be machined according to the shaft where it is mounted. If you need a pulley to replace an existing one or to build a new drive, send us the part number and the shaft data.

This pulley has a 500 mm outside diameter, 6 grooves and section B. Section B is a classic narrow-profile V-belt, and the 6 grooves allow transmitting more torque than a pulley with fewer grooves of the same diameter. The 500 mm diameter gives a low drive ratio if the driving pulley is small, and a high tangential speed, so it is advisable to check balancing and alignment before mounting it. The part is supplied without a finished bore, ready to be machined according to the shaft.

It is used in belt drives where a shaft needs to be driven at low revolutions and with good torque: hammer mills, horizontal mixers, screw compressors, vibrating screens, belt conveyors and pumping equipment. It also appears in old machines where a worn or cracked pulley is being replaced. In those cases, the important thing is to respect the diameter, the number of grooves and the belt section, because changing any of those values modifies the equipment speed and the power it can transmit.

To select the pulley properly, take into account the shaft diameter, the bore length, the type of keyway and the balancing. If the shaft turns fast, dynamic balancing is important to avoid vibrations. Also check the center distance and the belt length: if you change the pulley diameter, you may need another belt. The alignment between pulleys must be square so that the belts do not come off or wear on one side. If the equipment works under heavy load, it is advisable to use all the grooves with belts of the same length.

If you need a nearby size, a different diameter or fewer grooves, it can be manufactured. Send us the current part number, the outside diameter, the number of grooves and the belt section. It also helps if you tell us the shaft diameter and the type of keyway. With that data we will quote you an equivalent pulley or an intermediate size. If you do not know the section, measure the belt width or send us a photo of the old pulley and we will identify it.

To request a quote for the 500 6B pulley, send the part number by WhatsApp to MR Accesorios Industriales. If you have doubts about the section, the number of grooves or the bore machining, write to us and we will help you define it. We work with in-house manufacturing, so we can adjust the part to what your equipment needs.
