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

I typically buy these else where and this is my first purchase with this Vendor. Typically I get 608s and they are well lubricated but, also feel very clean and resistance free. These however were VERY lubricated and almost to much to where it was hard to clean. They also did not spin as freely as one normally does that I am used to. Perhaps a bad run.

Bought these for a filiment guide i was printing. 4 stars only because they arent high end bearing but they are excellent value and come in 2 plastic tubes for storage. Must have for 3d prints

Used to replace bearings in a rollator walker.

I bought these to use for 3D prints instead of skateboarding, so my review doesnt necessarily reflect their intended use. Ive noticed for about half of these bearings, they tend to bind up and stop spinning at lower speeds. And they dont come with any greese or oil in them as far as I can tell. Ive sprayed silicone lubricant in them and that seems to make some of them work better, but most of the problem bearings still bind up at low speeds. They all function, but if you want extremely smooth and reliable bearings, Id suggest you look somewhere else. They functioned just fine for my project, but I think the quality control could be better.

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 bought these bearings for the fan motor in my bathroom. I used a proper two-jaw puller to pull off the old bearings and to my surprise these new bearings just dropped right onto the shaft, even though I had to use a puller to pull them off. Once installed, they were pretty rough to turn over, which is fine because I expect the grease to have to melt and turn into oil to lubricate the balls themselves. Once installed, the motor was kind of hard starting, and once it was going it was extremely loud. Much more loud than the old bearings that were in there. I would not recommend these for use in a motor of any type, unless noise is not a factor.

Bought these for a custom fidget spinner. With the original grease, it spun around twice. Two rotations. I removed the dust covers and grease and they worked much better (though obviously dont do that on a skateboard)

I keep a stockpile of these on hand for my 3D printing projects; a lot of them require these bearings. I bought two tubes of 10, and took them all out. One in each tube was Crunchy, bound up and unusable. The rest seemed perfectly fine though. They still seem to have a thin film of oil from manufacturing, which protects from rust. Previous bearings from a different company didnt have the oil, and rusted up quickly in storage. Theres a bit of friction when spinning, but that might just be the grease used inside. I imagine you could soak them in oil or some kind of solvent to remove the grease and get them spinning freely. For the price, I wouldnt trust them for anything super heavy duty or something that human life depends on, but for small projects these are great.

I had several damaged bearings that could hardly turn and one where the shielding came off completely. Minor issues are the outer diameter is small by about 0.5mm and they wobble quite a bit. I use these for little 3D printer project but I doubt I would ever put these on a skateboard.

Great service
