Perfect for CNC
Used these for a DIY CNC build. No play and very quiet operation during high-speed moves.

Good fit
Fit my 8mm shafts perfectly. One bearing was slightly tighter than the others but broke in quickly.

Solid choice
Works as expected. Make sure your shafts are hardened steel to avoid wearing these out.
