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

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 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..

All Bearings making noise and 2 sets of bearing stuck

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.

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.

Was swapping these into a 1/5 rc car and out of the 20 I was lucky to get 6 that werent gritty. Well see how long they last but next time Ill spend a bit more and get some from a company that has some better tolerances. After blowing out the grease and re-lubeing they got a bit better but still not as smooth as I am used to. Plus side, they dont chirp but thats about it. Update - 7/31/21 - They chirp. Got gritty quick and not smooth. Look elsewhere.

Poor quality control. One of the bearings was kind enough to be missing a side shield so I could see the guts of the thing. The side wasnt in the tube, it must be somewhere at the factory. You can see the bearing to the lower right of that one is either made incorrectly or possibly inserted backwards? idk. Luckily they should work for my application since its pretty light duty.

Purchased these for use with my 3D printer, filament spool attachments. These worked great. Nicely sealed, lightly oiled and in a nice reusable container.

I ordered these to use as bearings for fidget spinners, I know. These were nice and cheap, and I wanted to give these a go. When they arrived, I noticed a couple had small spots of rust on the inside, so I emailed the company and they replaced them no questions asked and were very responsive and helpful. After decided the rust wasnt really that noticeable, I popped off both shields and then let them soak in gas so it would break loose all the grease (wasnt much). After letting them soak and shaking it a little, I took them out and let them dry. Afterwards, I sprayed them down with RemOil and took them inside. In a pretty light spinner, theyll spin for about a minute! I prefer these over the Bones Reds, simply because they spin longer and theyre cheaper. Overall, great product for the price and great customer service!

I got the bearing to use for the 3d print parts, but out of the box the bearing does not rotate too well. You may need some clean up and re lubricant depends on the use. Overall its OK for basic use.
