Sackorange 608 ZZ Skateboard Bearings, Double Shielded,8x22x7 Miniature Ball Bearings（Pack of 20)

These bearings dont seem to spin as freely as I hoped. Not sure if its due to the amount of lubrication but these are not smooth at all. For example you could use them in a fidget spinner but dont expect it to actually spin. Very tight so for that Im rating it lower.

Used to replace bearings in a rollator walker.

These bearings worked for what I needed them for (filament spool rollers). They were sticky at first but as other reviewers pointed out that was easy to fix. What cant be fixed is the variability of the tolerances. The diameter of the inner hole was inconsistent even on opposite sides of the same bearing. A few of them also came with the metal shields smashed. They can be removed pretty easily bit if you need them to be shielded I would look elsewhere.

one of the bearings came with a big gash in the shield, and all of them are really just not smooth. gritty and hard to turn.. going to try to repack but spend the extra 10 bucks and get some quality bearings.

No tienen la medida correcta

Its 608 bearings in a pack of 20, its pretty much exactly what it says. Came in 2 of those plastic tubes that are barely better than just shrink wrapping them but thats fine, thats all I needed :)

Ive used these for around a year in a few applications and overall if youre looking for something low speed with radial only (no axial) load then these will probably be fine. Anything high speed (greater than around 200 rpm) will quickly destroy the bearings and anything with any axial load will quickly destroy the internal balls. I used these in a cnc router as guide for lead screws and the axial load destroyed them in less than 20 total hours of use.

I used these bearings in a 3D print project and they are exactly what I wanted.

Everything is great as far as value for the money and thickness. One thing that could improve is the movement. Doesn’t spin as easy as I thought it would. But I’m also not a pro when it comes to bearings.

I bought these to replace old bearings in my bandsaw guides. They work fine, though I did have one in the package with substandard machining and you could feel friction when spinning it. I tossed that one and the rest were good.
