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

Some bearings roll smoother than others. Most of them are pretty stiff but you can oil them for some decrease in friction. The plus is the diametric tolerances are pretty good according to my calipers. OD 22 +.04 -.04, ID 8 +.03 -.05 which is great and they work great for my low speed purposes

I used this product for a wind spinner and it works better than ever. I also have several spares if needed. It saved my wind spinner from being trashed and I was so happy!

Good bearings. I have used these in a variety of 3D printed projects. They exhibit a little more friction compared to the bearings found in fidget spinners, but they will last much longer I am sure.

I love these for 3d prints! They dont spin forever like a fidget spinner would, but then again they shouldnt. The grease is viscous enough to prevent free/loose movement on the filament holder that I printed. If these spun easily and for a long time, I would have tangled filament! I suppose the grease could be replaced if you need a longer spinning bearing, but you might be better off getting another product.

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

Like others mentioned, these come packed in grease and nicely stacked in tubes. Once you spray a dab of WD40 on them they spin very freely and the dimensions are accurate from what I can see. I did receive one that was slightly damaged but the rest were all good. I would buy these again.

Great product for the money spent

very good for my job

I was worried at first because the didnt want to spin, but once I put them on my board, they (for lack of a better word) loosened, it was smooth cruising. Great product..

Guys just go to the skate shop. Ik you are looking for a cheaper way to skate, its not worth it. Buy REDZ if you have to but dont do Amazon skate stuff you will regret it. These were very loud, and you didnt get very far skating, but its enough to get you by.
