The QD JA-A bushing is a DODGE power transmission part that fits onto a shaft and gives you a solid seat for a pulley, gear or coupling. The QD design uses a tapered fit, so the mounted component stays concentric and transmits torque without looseness. Because the bushing carries the connection, you can swap a pulley or gear without pulling the shaft out of the machine, which keeps maintenance work shorter.

The code tells you what you are ordering. JA-A is one size and shape within the QD series, and the letters point to the taper dimensions and layout. The -A ending marks the mounting variant, so JA-A is not the same as other suffixes in the same family. When you order, give the full code as it appears on the part or in the manual.

You will find these bushings on conveyors, mixers, pumps, fans and machine tools, and in plants that run imported equipment or machines built to the QD pattern. Maintenance crews choose the QD style because replacement is straightforward and centering is reliable.

To pick the right size, start with the shaft diameter and the bore of the pulley or gear you are mounting. The split taper is drawn in by screws; as they tighten, the bushing grips the shaft and removes play. Clean the shaft and the taper, oil the screw threads, tighten evenly in stages, and confirm alignment. On equipment with heavy vibration, check the fit again after it has run.

Bushings from other makers often fit the same shaft and bore when the size code matches, but taper dimensions, hole positions and materials can differ. Before substituting, compare those details against the original. Send a photo or the old part number and our team will point you to a compatible option.
