3D Printable Bearings

thingiverse

I love the original design for how smooth the bearing works and how much load is able to bear, both radial and axial. In the end I needed more bearing sizes, and scaling the original to 200% caused it to have too much slack (even using the tightest version). Bearing was modelled from scratch using **FreeCAD**, I'm including **project file** to allow you to **generate any bearing size**. The results are surprisingly consistent with clearance equal between rollers themselves and between the rollers and races. If after changing the bearing size model can not be recalculated, try to: 1) decrease *Roller Maximal Diameter Height* - it is height of a wide end of a roller, values around or less than 1/5 of *Bearing Height* are OK 2) increase *Roller Minimal Diameter* - it is diameter of a roller in its narrowest slice, set a value a few mm lower than *Roller Diameter* Please leave me some feedback on what can be improved or if it has helped you in any way. Update 2020-12-15: *I've uploaded non-broken version of project file. Use FreeCAD 0.19+. Everything should be fine with parametric constraints now.*
