After a quick search, I found the info on the Spindle Bearings for the Head assembly for the X2

I ordered them from McMaster...
UPPER: $11.84
5972K47 Metric Steel Ball Bearing Double Sealed Bearing NO.6206 for 30mm shaft diameter

LOWER: $14.03
5972K85 Metric Steel Ball Bearing Double Sealed Bearing NO. 6007 for 35mm shaft diameter

I am going to use a threaded rod, scrap metal, some ingenuity and go through the process of bearing removal and installation. I will post pics of the process. I have never done this before so wish me luck.
