These weld rings can be used in all sorts of fabrication projects but are most often welded to "A" plate, rough stock bore sprockets.
These weld rings allow the user to mate a "Browning" or "QD" split taper lock bushing design to their project.
Welding tip: When attaching any weld-on hub to a plate sprocket, place 3 small tack welds in a triangular pattern and let cool. Check for accuracy, then weld the remainder in the same pattern so the sprocket does not torque from the heat, causing wobble on the shaft after installation Power-Link Catalog
