1/8" 0.125” ball bearing

thingiverse

I had some extra 1/8" steel ball bearings lying around, so I decided to create my own custom bearing design for a 3D print project I was working on. The inner diameter is exactly 10mm, with a round opening in the STL file, and the outer diameter is 21.4mm. The height of the bearing is 5mm. It perfectly fits 16 - 1/8" ball bearings. When assembling the bearing, the two center pieces snap together easily, but you'll need to add a small drop of super glue to secure it in place. I'd love to see how you're using this custom bearing! Please share your photos with me. Enjoy! Update: I've added an additional STL file for a modified bearing design used on a gearbox project. This new version has tabs on the outer ring and a hex hole for extra stability and customization options.
