The Dodge QD hub is the mounting component that connects pulleys, gears and similar drive elements to a power transmission shaft. Its split taper design simplifies centering and secure fastening, and allows removal without hammering the bearing or the shaft.

The QD series uses a part number to define the hub size and dimensions. In this case, that number is H-A. When selecting the complete assembly, the hub part number is matched with the required shaft diameter. Each QD hub accepts a range of shaft diameters, and a split taper bushing is tightened with screws to lock the assembly.

QD hubs appear in conveyors, mills, mixers, pumps, fans and machine tools. They are common in food processing, cement, petrochemical and aggregate plants, where pulley and gear drives need secure, repeatable mounting. Lifting equipment and production lines that require fast replacements also use them to reduce downtime.

For selection, consider the shaft diameter, the radial and axial loads, and the element you will mount. The taper bushing must be clean and free of burrs. Apply oil before tightening the screws in a crosswise, progressive pattern. Verify alignment with a straightedge or dial indicator, and check torque according to the manufacturer's table. Proper mounting helps prevent vibration and supports bearing life.

Dodge QD hubs can be interchanged with other brands that use the same taper bushing system, provided the part number and shaft dimensions match. This standardization simplifies replacement on existing equipment without modifying the mounting. If you need an alternative, MR can suggest a compatible option for your application.
