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

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.

I ordered these to use as bearings for fidget spinners, I know. These were nice and cheap, and I wanted to give these a go. When they arrived, I noticed a couple had small spots of rust on the inside, so I emailed the company and they replaced them no questions asked and were very responsive and helpful. After decided the rust wasnt really that noticeable, I popped off both shields and then let them soak in gas so it would break loose all the grease (wasnt much). After letting them soak and shaking it a little, I took them out and let them dry. Afterwards, I sprayed them down with RemOil and took them inside. In a pretty light spinner, theyll spin for about a minute! I prefer these over the Bones Reds, simply because they spin longer and theyre cheaper. Overall, great product for the price and great customer service!

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.

I wish I had read more of the reviews. These are packed in such heavy grease that they are practically impossible to use out-of-the-box. They do not spin freely. Some reviewers have said this is actually preferable for industrial use. That may be. The product name says Skateboard Bearings and they are unusable for that purpose. Others say to take degreaser to these bearings and re-lubricate them. Again, that might be fine for some folks, but I bought a product, not a project. These are going straight in the trash and Ill buy free-spinning bearings from a local skate shop.

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

They work. Theyre decent quality but from what I could tell, not for high precision applications. The center bore wasnt always exactly centered and several spun rough but did work and will be sufficient for my needs. Id guess these were pulled from old equipment as many of the ones I received showed signs of previous external wear. I also had to clean these up as they were sticky to the touch, smelled awful and were initially very difficult to spin.I soaked half in Mineral Spirits and the other half in Acetone. Both methods seemed to clean these up really well and they all spun freely after cleaning. Ill likely repack with better grease when Im ready to use these. For my project, im more interested in lowest possible resistance and not concerned with speed or

very good for my job

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.

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.

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.
