20 PCS 608 -ZZ Ball Bearings – Double Metal Sealed Miniature Deep Groove Ball Bearings (8mm x 22mm x 7mm) (608 ZZ)

Amazon saves the day, great value and good quality. Brand new and packaged in clear plastic containers so you can put them on the shelf and see what you got easily.

We use these bearings on our 3d printer projects (Bambu and Qidi) to print functional household and decorative items. We always look for well priced quality additions for our printing needs and always end up on Amazon. Highly recommended!

I purchased these to use in 3D printed components. Many reviewers commented on how they don't spin freely and some feel gritty. Bearings are made to bear a load and allow it to spin smoothly, and for this they work fine. I am using them for 3D printed projects and haven't been disappointed yet. For skating I would recommend spending more and buying a set of quality skate bearings - I have a set of quality skate bearings I've been rolling on since 2012 (~8 years now). You'll feel the low quality with every roll, I wouldn't count on these to either last as long or be anywhere near as quick and smooth as name-brand skate bearings, but they're significantly cheaper and almost disposable while still offering a relatively frictionless roll compared to plastic-on-plastic that keeps my designs from wearing out prematurely.

Used these on a little 3d printing project, and they roll great, no issues, and they are the right size.

It's convenient that there are many pieces and it came to our scooter

Not the smoothness I had expected. They spin but take more effort than others that I’ve used. Already greased so that’s not the issue.

Good deal

Worked well on my wind spinner
