A Dodge QD hub is the interface that lets a pulley, gear or similar transmission element sit on a shaft, working together with a QD taper bushing that is drawn tight by screws. Because the joint is made with screws rather than force, the element can be fitted and removed without hammering and without scoring the shaft. MR Industrial Accessories LLC supplies this line to maintenance and purchasing teams throughout the United States and in several Latin American countries.

The letters QD point to a standard family in which hubs and taper bushings are matched to one another. Each hub part number tells you which bushing size it takes and how many mounting screws are involved. Before ordering, confirm the shaft diameter, the bushing type you intend to pair it with and the number of screw holes or grooves. If the code on the part is unclear, send it to us and we will help you read it.

Typical users are plants in food processing, textiles, chemicals and material handling, where torque has to be transferred and components are swapped out regularly. Conveyors, mixers, pumps and industrial fans are common homes for these hubs. Since the pulley or gear can be changed without pulling the shaft, production stops tend to be shorter.

Selection comes down to three things: shaft diameter, the torque the drive has to carry and the QD bushing type that matches the hub. During mounting, the screws press the bushing against both hub and shaft, so the tapered faces should be clean and the specified screw torque should be respected, with alignment checked afterwards. A light film of lubricant on the screws pays off the next time the joint has to come apart.

Hubs carrying the QD name from different manufacturers can generally be swapped when the bushing size and mounting pattern agree. To match a hub already in service, line up the bushing part number, the screw count and the principal dimensions. Our team can point you to the hub that fits your equipment so neither the shaft nor the driven element has to be modified.

Send the part number, or a photo of the part, by WhatsApp or email and we will come back with a quote and, if you are considering a different setup, a compatible option. We serve customers across the United States and in Latin America with power transmission components.
