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

Theyre basic sealed bearings from China that youre not supposed to open. They dont run fully smooth out of the container. If you work the bearing for a while, it does improve. But without disassembling and cleaning, it wont spin like a fidget spinner. Im using it for a roller on my Ender 3 printer, and for that its been fine. So just decide how smooth you need it to be. 3 of 5 stars overall.

As others have mentioned, out-of-the box these bearings do not spin well at all. Theyre covered in a viscous oil thats most likely there to protect against rust. Just run some 3-in-One Multipurpose Oil through them a few times; this will both clear out the thick oil and lubricate the bearings as well. They seem to be just as high quality bearings as most others.

Pretty stiff and sticky out of the tube. A little wd-40 to clean them you and loosen them and they work just fine.

I did not use these in a skating application. I can not speak to their durability in that application. There were used in a spooler that required a set of 608 bearings that could simply roll smoothly at low speeds. All dimensions were within stated specs for 608 bearings. They come pre-greased in tubes of 10. No complaints and would order more for additional projects.

These are nice bearings, but despite the positive feedback, DO NOT use these for fidgets. I bought these so I could 3D print some spinners and resell them but these were just spinning disappointments. I gave 4 stars because this is advertised for skating, not fidgeting.

Got these for 3d print use, some are definitely smoother than others but for what i needed them for, perfectly fine. If using for a skateboard etc, might wanna seek something of better quality unless money is super tight

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.

Inexpensive option for non performance related projects where the bearing must spin but does not need to spin freely/loosely (ex a carousel vs a fidget spinner). -- 100% worked for what I needed but will likely look for a different freer spinning bearing on my next purchase.

one of the bearings came with a big gash in the shield, and all of them are really just not smooth. gritty and hard to turn.. going to try to repack but spend the extra 10 bucks and get some quality bearings.

Used on rollators for a 270lbs person. She likes to try to get the thing to turn on the none turning wheels while shes sitting on it and twists the bearings apart. After destroying 3 rollators because I didnt know what part to buy, these make it not matter. Pop out the old one, push in the new one and off we go again. As far as durability, she has destroyed one of these yet going on 8 months. So better than the original.
