The QD JA-A bushing from DODGE is a power transmission component that mounts on the shaft and serves as the base for securing pulleys, gears or couplings with the QD system. Its design allows a tapered fit that guarantees concentricity and torque transmission without play. It is used in equipment where the pulley or gear needs to be changed without disassembling the shaft, which simplifies maintenance. MR Accesorios Industriales supplies it in Buenos Aires, Argentina.

The JA-A designation identifies a bushing from the QD series by DODGE. In this nomenclature, the letters indicate the size and configuration of the taper, and the -A suffix distinguishes the mounting variant. The JA-A code is used to order the exact part: with that data the bushing is identified without ambiguity. If you need another size from the same series, write to us on WhatsApp with the code shown on the equipment.

These bushings are used in conveyors, mixers, pumps, fans and machine tools. In Argentina we see them in food plants, cement plants, tanneries and maintenance workshops that replace pulleys and gears. The QD series is common in imported equipment and in locally manufactured machines that adopted that standard for its ease of replacement and good centering.

To select the correct bushing, take into account the shaft diameter and the size of the pulley or gear you are going to mount. The QD system uses a split taper bushing that is tightened with screws: when tightened, the bushing compresses the bushing against the shaft and eliminates play. Check the alignment and tightening torque, and lubricate the thread before mounting. If the equipment runs with a lot of vibration, periodically check the fit.

QD bushings from different brands are usually interchangeable if the size code and shaft diameter match. However, tolerances and materials may vary between manufacturers. To replace a DODGE bushing with another brand, compare the taper dimensions and the hole locations. If you have doubts, send us a photo or the original part number and we will indicate the compatible alternative.
