A QD bushing is a tapered sleeve that sits between a shaft and the bore of a hub, whether that hub belongs to a pulley, a gear, a sprocket or a coupling. Tightening its screws draws the bushing into the hub, which grips the shaft and locks the assembly in place. No extra machining is needed, and the joint can be taken apart later. Beyond holding the hub, the bushing transmits torque and keeps the hub centered, which makes it a practical building block in power transmission work.

DODGE organizes the QD range by bushing size, and a given size covers a band of shaft diameters. In a series part number, the figure you see points to one specific pairing of size and shaft diameter. The SDS, SD and QD series separate the sizes by how much torque they carry and by the hub bore they fit. When you are picking one, the shaft diameter and the hub size of the equipment are the two figures that decide the rest.

Typical installations include drive pulleys, gears, chain sprockets, couplings and the hubs of process machinery. Food, cement, steel, paper and mining plants use them, as do material handling systems, along with pumping, ventilation and conveying equipment where the tapered joint has to carry load and still let the hub come off without harming the shaft.

Selection comes down to shaft diameter, hub size, torque and load type. During mounting, work the fastening screws down evenly and stay with the torque figure set for that size. Wipe the tapered faces clean, put lubricant on the threads, and line the shaft up with the hub; those three steps are what keep the joint from slipping or vibrating. In dusty or damp areas, it also pays to look at how the assembly is sealed and protected.

Bushings built to the same taper standard as DODGE QD parts can be swapped in, as long as size, shaft diameter and screw count line up. That is what makes replacement on existing equipment straightforward and lets hubs and bushings from different sources be paired. The reliable way to confirm a match is to put the original part number next to the shaft and hub dimensions of the machine.

For a QD bushing on a pulley, gear or coupling, send the part number or model by WhatsApp or email to MR Industrial Accessories. The team will quote the DODGE bushing and, if the equipment carries another brand, point out the equivalent. They also help with selection and replacement of power transmission parts for customers in the United States and Latin America.
