Neat, though I wonder how long the recirculation ball units will last with wood dust etc, I spent two years supporting IBM production lines with the same bearings in 'carrier pallets' running of s/s rails in a class 100 cleanroom, averaging 3 sets of bearings a day across 100 units due to wear and tear. Igus drylin bearings might be a good upgrade? https://www.igus.com/product/1196?artNr=OJUM-01-10
