EXERAUO 100 PCS 608-ZZ Ball Bearing 8mm x 22mm x 7mm Double Metal Sealed Shielded for Electric Motor, Skateboards, Inline Skates, Household Appliances

I frequently tinker on random projects, and often need bearings for various purposes.These are perfect. They are consistently sized, and work great.I wouldn’t recommend these for making a super long-spinning fidget spinner (the lubricant in these is a bit thick I guess), but if the spinner is heavy enough, these could work for that too.

These bearings come in plastic rolls and for the price to quantity these have very good value. Useful in all manner of projects, these bearings roll very smoothly. However, they aren't completely free moving and it does take slightly more than expected force to spin, so lighter projects like fidget spinners may not work as smoothly as intended.

I use a lot of bearings this size (often called skate bearings) in my 3d printing projects, so this bulk supply of 100 bearings should keep me going for quite a while. Perfect for filament holders or other light-duty applications that don’t need high precision. Recommended

Useful for all kinds of projects. I intend to use some of these to make a router sled to flatten wood. Super great price for 100 bearings. I haven't checked all 190, but the ones I checked all run smooth. Feel like good quality bearings.

They come well-protected in plastic tubes. The bearings have been smooth rolling so far. I've used some for a 3D filament respooler and some wheeled toys. I plan to make a router sled for flattening slabs next and these should work well! No defects in the ones I've tested.
