uxcell 20pcs MR63ZZ 3mmx6mmx2.5mm Double Shielded Miniature Deep Groove Ball Bearing

These little bearing are well-engineered, self-sealed, and lubricated. I've used them in many projects and have ordered them several times over. Highly recommend them. They are also very strong.

I used these to create more realistic looking freight and passenger train cars' bogies (trucks). They roll better than the standard Lego wheel holders. The fit in a technic pin hole with a little bit of extra force.

I bought these for an RC Boat project to use on the output of the drive shaft. These are not stainless and rusted after the first use. They continued to work after breaking the rust free so no problem for me. Will buy stainless next time. Spun up to 25,000 RPM with no noise or vibrations of any kind. Amazing little bearings.

Good quality and exactly what I needed. Fair price as well.

Good little bearing. Used these in a small robot project. Nice price too.

I originally bought these fit spectacularly and spin very easy. It wasn’t until after I attempted to install axles hat I realized the ID is not 2mm, but 1.9. Therefore, appropriately sized 2mm axles don’t fit. I bought a lot of these, sure I will find a use for them in a different project, but can’t use them for what I wanted as the inner diameter is wrong.

Good bearings for fishing reels

I need a 6mm OD bearing with a 3mm ID. These bearings have a 5.98mm OD (acceptable) but a 2.92mm ID. As a result, you can't get a 3mm shaft through it. That's the whole purpose, isn't it?..

The media could not be loaded.  Ich mach damit vorwiegend meine BlueBrixx Zug Achsen. In der Regel passt das perfekt, gelegentlich muss man ein bisschen mit dem Hämmerchen nachhelfen aber das Ergebnis ist super.
