608 ZZ Ball Bearings(10PCS), 608ZZ Metal Double Shielded Miniature Deep Groove Skateboard Ball Bearings (8mm x 22mm x 7mm)

They work great so smooth, clean ride my son is happy.

they are actually a bit smaller than the ones theyre replacing. small enough that they wouldnt fit on the 8mm bolt/axle of the walker i was working on. I replaced the bolt with a 5/16 and made it work. they are undersized by a few thousandths of an inch. the OD is also smaller than the original ones although they have the exact same number designation on them! China, you need to check your calipers and machines!

These arent awesome. They worked for what I needed them for (a filament holder for my 3d printer). I didnt need too much spin for that. Then with all the extras my kids thought it would be fun to print a fidget spinner. It doesnt spin well for that. But they did get the job done.

worked great for my 10 inch craftsman bandsaw blade guilds

They roll like they are supposed to. Shielded (ZZ) my preferred 608 version

As stated in description

These bearings are definitely not free spinning and feel very sticky but should be good enough for repairing the wheels on my mother-in-laws Drive brand Rollator walker.

I used the bearing in a low load, low speed application, so I can speek to regulat use, but they arrived clean in a sealed pack and are very low friction.
