The QD bushing is a tapered fastening element that mounts between the shaft and the hub of pulleys, gears, sprockets or couplings. It is installed with screws that, when tightened, compress the bushing onto the shaft and lock it against the hub, achieving a firm, removable connection without additional machining. It is a key part in power transmission because it transmits torque, centers the hub and simplifies component replacement in industrial equipment.

The DODGE QD designation is organized by bushing size, and each size accepts a range of shaft diameters. In the series part numbers, the number identifies the combination of bushing size and shaft diameter. The SDS, SD and QD series group the different sizes according to torque capacity and the hub diameter they support. To choose the right one, the governing data are the shaft diameter and the hub size of the equipment.

In Argentine industry, QD bushings are used in drive pulleys, gears, chain sprockets, couplings and process equipment hubs. They appear in food, cement, steel, paper and mining plants and in material handling systems. They are also common in pumping, ventilation and conveying equipment, where a tapered connection is needed that withstands loads and allows the hub to be removed without damaging the shaft.

To select a QD bushing, take into account the shaft diameter, the hub size, the torque to be transmitted and the type of load. Mounting is done with the fastening screws, tightening evenly and respecting the torque recommended for the size. Cleanliness of the tapered surfaces, lubrication of the threads and alignment between shaft and hub are key to avoiding slippage and vibration. If the equipment works with dust or moisture, it is advisable to check the sealing and protection of the assembly.

DODGE QD bushings are interchangeable with those of other brands that use the same taper mounting standard, provided the size, shaft diameter and number of screws match. That compatibility makes replacement in existing equipment easier and allows hubs and bushings of different origins to be combined. To confirm equivalence, the safest approach is to compare the part number of the original bushing with the shaft and hub dimensions of the equipment.

If you need a QD bushing for a pulley, a gear or a coupling, send the part number or model by WhatsApp to MR Accesorios Industriales. We will quote the corresponding DODGE bushing and indicate the compatible alternative if the equipment is another brand. In Buenos Aires, Argentina, we support the selection and replacement of power transmission components.
