3D Printing Bearing Sizes - superjamie/lazyweb GitHub Wiki

I might redesign this at some point. For now I'll just keep a few useful shaft diameters.

Pay attention to the size for a given LMxUU bearing, not all Igus series are replacements/over/under.

RJZM-02-06 12mm 22mm N/A compact sleeved (replacement )

8mm
