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

Excellent bearings. They run smoothly with no issues. They come in little tubes, which is great. Overall, an excellent product.

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 expected these would spin. They do not. They turn well and do not hang. They turn very easily but just not enough to make them spin. If that’s what you’re looking for, you need to find something else.

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.
