Ball Bearing Slide for 2020 Extrusions using 603 Bearings

This is a modification of LoboCNCs linear slide bearing for 2020 extrusion rail which will allow you to use 603 bearings. Using 603 bearings also allow you to select the use of POM nylon glass ball bearings so you don't need lubricant and you won't have issues with steel bearings cutting and pitting into the Aluminum extrusions overtime, This design is not proven yet; feedback is welcome.

If you decide to use the POM nylon glass bearings, make sure you lightly set the tension screw on each size to not overload the bearings; which you should be careful of with any bearings this small.
