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

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

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.

Everything is great as far as value for the money and thickness. One thing that could improve is the movement. Doesn’t spin as easy as I thought it would. But I’m also not a pro when it comes to bearings.

All Bearings making noise and 2 sets of bearing stuck

I used these for demo motors to show kids how things work. The first thing I did was pull the grease covers (shields) off and wash the bearing with acetone to clean them. Be aware that the set that I purchased did not come packed with grease, which for me was great - less cleaning. I want the kids to see how the bear works. The great thing is that still today after thousands of rotations and hours of running time, none have failed.

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 read a lot of reviews stating they dont spin very well. This is 100% true. When you get them, they are gummy. A spray of WD40 and working them a bit will have them spinning nicely in no time. I dont use them for whatever they were manufactured for, so I cant say if they are good for whatever that is, but for hobby projects or 3D printed stuff, they work swimmingly.

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.

Currently using one as part of a 3D printed stabilizer for my Z-axis on my Ender 3. Its the perfect fit allows rotation and little wobble. Printing has been going a bit faster and cleaner.

They pretty sticky out of the box but thats just because theyre packed with grease, a quick spray with some simple green followed by some compressed air and some oil frees them right up. You could skip all that and just blast them with WD-40 but I like to use actual bearing oil. That said, the tolerances are actually kinda terrible, they have quite a bit of slop in them and they feel rough when you spin them. I suspect thats why they over grease them, to hide the bad tolerances and low quality balls/races inside. I dont use them for anything load bearing or fast speeds, these are just used for the filament roller guides on my 3d printer.
