Hello !
I think you (or me) has misunderstood..
The bearings on x axis your long axis should be wider preferably so that the tip of the cutter is between them when viewing the machine from the side.
The y axis bearings on gantry can be closer.

If you use 90x90x4 steel with no welding, how will you close the ends to be able to bolt there?
