The DODGE SF-A QD hub is a power transmission component that mounts on the shaft and serves as a base for securing pulleys, gears, sprockets and other rotating elements. Its split taper design allows a firm, centered fit, making assembly and disassembly easier without hammering the shaft or the component. It is a key part in production lines where torque must be transmitted safely and alignment maintained.

The SF-A designation identifies a hub from the DODGE QD series. In this nomenclature, the letters indicate the size and taper type, while the A suffix indicates a construction variant within the series. The SF-A code is used to order the specific hub that matches the QD bushing of the same size, so the assembly is perfectly paired. If you need to replace an existing hub, the code stamped on the part is the data that speeds up the quote.

QD hubs are used in a wide variety of industries in Argentina: food plants, cement, steel, paper, textile and agro-industrial facilities. They are found in conveyors, mixers, pumps, fans and mills, where they secure the pulley or gear to the shaft reliably. Their split taper mounting allows the element to be removed without damaging the shaft, something highly valued in scheduled maintenance tasks.

To select the correct hub, consider the shaft diameter, the size of the QD bushing you will use and the type of load to be transmitted. Assembly requires thoroughly cleaning the tapered surfaces, checking that the bushing and hub are free of burrs and applying the tightening torque for the screws according to the manufacturer's table. Careful alignment between shafts prevents vibration and premature wear. Lubrication of the taper is not necessary, but keeping the part free of corrosion is.

DODGE QD hubs are interchangeable with those of other brands that adopt the same dimensional standard, as long as the bushing size and shaft diameter match. This compatibility makes replacement in existing equipment easier without modifying the mounting. If you have doubts about the equivalence, write to us on WhatsApp with the code of the original hub or the shaft dimensions and we will indicate the compatible alternative.
