Good quality, tight fit
Quality seems high but the 10mm size was a bit tight on my shaft initially. Loosened up after use.

Perfect for my CNC project
These bearings slide smoothly on the hardened shafts. No binding issues at all.

Excellent value
Bought a set for my 3D printer upgrade. Much quieter than the old ones.
