Antrader 10Pcs 608 Steel Ball Bearings 8 x 22 x 7mm Fidget Spinner Bearings

Size 6201Z was perfect. Double shielded, very smooth and quiet, perfect replacement for OEM NSK bearings. The last picture shows it installed in the generator. Press fit was perfect, just as expected, and indistinguishable from the original.

Amazing, for the price, low friction 608 bearings. It can be difficult to find decent low fiction bearings in any price range. I've purchased a ton of them from different suppliers and most of them are far from low friction. Not to mention many companies call their bearings low friction when they're full of grease that causes a lot of friction and if you clean the grease out the tolerances are pretty bad and they vibrate when spinning at high speeds. Would I put them in a skateboard, no. They're not sealed and I don't think that's what they're designed for even though they could probably handle it for a while. Anything that doesn't take a severe load and needs to be very low friction, yes I would use these and do. They work great for low load conveyors, almost too well for a lazy susan, fidget spinners work great, they also work well in low friction 3D printing spool holders. I've yet to receive a bad one. I hope the company can keep up this level of quality and I'm very surprised this doesn't have more reviews than it does.

was as advertised I can't really is this is my first set from the the makers of these but they actually better quality than I thought they were going to be

Fast and smooth. I have tried several bearing on AMZ and these so far seem the best. I have owned them for about a year and they still seem just as good as when purchased. I cannot say how they would do as a fidget spinner but for moving parts, in my case 3DP parts connected to a motor, it performs as great. I am currently buying another set.

I use these for 3D printed fidget spinners, they seem to work pretty good but don't spin as long as I would have hoped. They also don't seem as smooth as some other bearings. For the money, I've been happy with them and I have purchase more since the original purchase.

Who knew skateboard bearings were a perfect fit for a bandsaw? I purchased a secondhand Grizzly bandsaw that had been neglected for a while. Apparently, someone had set a paper cup of Coca-Cola on the cast iron table and forgot about it. For a LONG time. cup dissoved, acid at into the cast iron, and ran down into the set of guide bearings. The table I was able to get back to 90% original, but the bearings were seized. Grizzly very proud of a set. These were the exact same bearings for less than the shipping from Grizzly. Perfect fit and function. And with this set, I have spares left over!

Finally got to do some 3D prints using these, they work great! Bearings are smooth and work great for spinners and fidgets. Keep some in stock for your prints.

Great product. Working very well for my 3d prints
