Review on 🔩 High-Performance Uxcell Shielded Miniature Bearing – 3mm x 10mm x 4mm by Jeff Sorensen

I got them for a small project I'm working on to make a 3D printed 4 cylinder engine. the quality seems to be good. I won't put too much stress on them as there is only a small electric motor that moves the parts, but they fit well and seem more than able to handle the stress I've put them through. haha
