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.

These are an exact fit bearing for the FL Sun cube 3D printer I had. Unfortunately the quality, although better than the originals, still included ones with defects. I replaced the four bearings and found that three of the four had bad spots in them. I sorted through the first package of ten and found that 4 were bad, with a spot that clicked when the shaft was turned. Of the six remaining, I chose the best four and they are currently working fine. Note. These are NOT sealed bearings and do leak lubricant. However, because of this, they can be flushed and re-lubticated. I do not recommend them for Inline skates or any machinery that is precision, critical, or may be exposed to contamination such as dust and dirt. They are low cost and low quality. OK for the price, but thats all.

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!

very good for my job

They wouldn’t last long if using them everyday They are not like USA or German bearings

packed with sticky grease to make the bearings appear more precise. Once you remove the greese with a good degreaser (major effort) and replace it with a light oil you notice a lot of play in the bearings dimensionally. If your just looking for a cheap bearing that spins fast then these will do. If your using these for any projects that require some accuracy on center of bearing look elsewhere.

Its 608 bearings in a pack of 20, its pretty much exactly what it says. Came in 2 of those plastic tubes that are barely better than just shrink wrapping them but thats fine, thats all I needed :)

Im using these for 3D printing in the creation of Filament Spool holders. These are perfect with just the right amount of friction so that they roll nicely. I did not clean the bearings but used as is.

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.
