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

I used these bearing to repair some Adult Assistance Walkers, for the elderly people that reside at the Adult Foster Care/Assisted Living facility, where my wife works at. They were going to throw them out, because the wheels were wobbly. She figured that I could probably fix them & save them from going into the dumpster. These fit & worked perfectly! I was happy & pleased with the quality of the bearings, especially for the price. Be sure to check the size bearing that you are going to need for your application or repair. As they do come in very many different sizes. I must add...Shipping was Super Crazy Quick for these too! I was able to repair 3 walkers with this bearing package/kit. I made the Senior Citizens at the facility very Happy! Being able to use Safe, Smooth Rolling Walkers again. I was a Hero in my wifes eyes...even for one day...so, Ill take it!

They roll. Several of them have dents in the steel seals, but honestly, as long as they turn smoothly, I dont care.

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.

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

It works acceptable, but the lubrication used was gummy and sticky. The packaging was just a plastic tube that doesnt really seal which wouldnt be a problem if they used better lubricant. I havent used them for any demanding tasks, but they work for random projects

These bearings worked for what I needed them for (filament spool rollers). They were sticky at first but as other reviewers pointed out that was easy to fix. What cant be fixed is the variability of the tolerances. The diameter of the inner hole was inconsistent even on opposite sides of the same bearing. A few of them also came with the metal shields smashed. They can be removed pretty easily bit if you need them to be shielded I would look elsewhere.

They come coated in thick greasy shmoo and dont spin well at all. but a few liberal sprays of WD-40, spinning it a few times in-between sprays, and they spin real nice. about 4 out of 5 spin well so far, some have what feels like metal bits in them that prevents super smooth spin. i havent taken the lid off of them, just sprayed the sides, and the WD-40 works its way inside. for 10$ getting 20 of these, even if only half worked, i would have been happy. im using these for robotics, not skateboards. packaging is a little lacking, but ive seen worse

Used with 3d printing projects. Sizing seems accurate, and rotating action seems smooth with low friction. Looking forward to finding more uses and buying again, cause its FUN making stuff

These are labeled as 608ZZ and are double metal shielded. The ability to spin freely is somewhat limited for some reason. I dont know if the grease inside is too thick or what, but if youre looking for a bearing for a fidget spinner then you might want to look elsewhere. On the other hand, there is no play between the inner race and the balls and outer race, so I cant say they are sloppy loose either. I think they are a god value for the cost as long as you are not wanting something that is going to spin freely for any length of time.

I had to make a bass string winding machine for musical insterments and these bearings are just what I needed. In the pass bearings like these were in windmills, worleyjiggs I think its what they are called forgive my spelling! Since you cant find them in local stores you have to depend on reviews like these. YES I WILL USE THEM AGAIN. Good luck!
