New stainless steel eccentric spacers for your next CNC, 3D printer, or motion control project.
The 5mm bore is 0.79mm off center to allow you plenty of adjustment when tightening your wheels to your rail. The boss is the standard 7.11mm (0.28″) diameter, and is 2.5mm long. The main body of the spacer is 6.35mm (0.25″ wide). The outside of the spacer body is marked to indicate the “tight side” of the adjustment. See the drawing for more details. These are often used with 625 bearings or 625 bearings and wheels.
The MillRight M3 kit comes with all the eccentric spacers that you need for that machine. Order these for your other projects.
