This little tool helps you press LM10UU linear bearings into the aluminum housing on your 🥰 Prusa Core One's Y-axis assembly. It makes sure the bearings are fitted centered in the CNC machined housing. As you need to heat up the aluminum housing and cool down the bearing before pressing it in, with this tool, you can do the press-in process quickly and nail the alignment during that critical temperature window.
Variants
Multiple versions of the bearing clamping tool are available with different inner diameter. For standard LM10UU bearings as shipped by Prusa the 9.15mm version should work fine. But I found the fit was a bit tight with some alternative bearings like Vesconite polymer bearings. So I created some variants with a 9.20mm and 9.25 inner diameter.
Assembly
… follow the pics. 😎
| Note: During installation, check the alignment of the balls. The printed part has markings to help help you (picture 4). Ensure that both printed parts “aligned horizontally” while pressing the bearing in (picture 5), and everything will align correctly. |

| Disassembly: To remove the bearing from the housing, heat the parts to about 100°C. The different thermal expansion rates of aluminum and steel will help you push the bearing out (more) easily. |
