Bearings were also an issue, the only ones I had where some scavenged from old milling cutting tools (5x9.5x3.2 or something like).
Unfortunatelly, there's quite some work after printing.
2x Flat Head Machine Screws are required for each spring I used M3x10mm, a little bit longer should be also ok.
For the bearing I also used another M3x10mm and due to the dimensions of those bearings I found, I also used 2x M3 washers (not to eliminate but to decrease the gap up to a minimum.
You shouldn't need the tubes/bushings/shells/whatever if you use the right bearings.
Do not force anything* or you'll end up breaking it, use the OpenSCAD (full of parameters) if something doesn't fit.
(*) The only place where force MUST carefully be done is to mount the springs.
