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

Llego en buen estado, lo compré para regalarlo pero debe bien me gusto

I mainly used mine for a spool holder. For price, quality and quantity, cant complain. I measured with my caliper and everything was within spec for my scenarios.

As stated in description

We have some bicycle wind spinners that were worn out from all the wind where we live. My husband replaced the ball bearings , they are all spinning away again.

For my Walker

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!

I got these for items for my 3D printer (filament guide, roll holder, etc.). I hoped they spun a little better. They work in the filament spool holder and a guide. thumbs up.

Smooth

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.

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.
