1522 Series 8mm ID Spacer (10mm OD, 9mm Length) - 4 Pack

This 9mm length, 10mm OD spacer is able to slip over an 8mm shaft—whether that’s a round shaft, REX™ shaft, threaded rod, or even a lead screw—to create space between components. When you run it against a bearing, the spacer will only contact the bearing’s inner race. This allows your project to rotate smoothly.
