An experimental 3D printable linear bearing that uses circular slides to (in theory) reduce surface area and friction. This type of bearing (in theory) should show equal performance of 3D printed linear fin bearings while lasting longer and being able to bear more weight. Use the customizer to match your own size bearing.

The photos show a standard size LM8UU bearing using four sliders. I have not tested the effects of the number and radius of the sliders, it would be awesome if someone could test them and let me know the results.
