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

I am not using them as they are intended to be used. I am over speeding the bearings. But they are holding up

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.

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 :)

Great service

Filled with some of the cheapest thickest grease they could get. Takes a ton of effort to get these spinning smooth. Cleaned out the grease with brake cleaner, and used an oil meant for ball bearings and they spin much better now, but nowhere near high quality bearings.

The ball bearings did do what they were supposed to, but didn’t do it well. The bearings were heavily greased to the point of no free spin. With a nice isopropyl bath they end up working for what I needed them for.

They work as designed and were cheap, used in a 3d printed project.

Two out of 20 are very rough and poorly made. Quality control is questionable. All bearings needed break-in to spin. About 5 spin well, rest are just mediocre.

Used to replace bearings in a rollator walker.

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.
