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

These bearings are smooth and seem fairly well made. Unfortunately the manufacturer used a very thick lubricant — probably a heavy grease — so theres quite a bit of friction and they dont spin for very long. If you want them to spin freely with minimal force, youll need to clean out the grease using mineral spirits or maybe WD-40 and then replace it with a lighter grease or maybe just some oil. Ill probably try a different brand next time in the hope that I find some that dont need their lubricant replaced.

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

They seem loose and wobbly and many of the shields protecting the bearings from dirt are dinged up like they were installed by hand by someone in a hurry. A bearing should only spin and not move in other directions. I plan to use them for wheels on parts bins, so theyll work for that, but I wouldnt bother with them again.

These came pretty sticky thanks to whatever grease they oack them with, not sure I can actually use these for anything than a filament guide for a 3d printer, like most have said here it seems some cleaning and wd40 goes a long way but jt doesnt make up for it and if you dont own wd40 for some reason then youl have to spend more money on a can of that first before using them.

Used on rollators for a 270lbs person. She likes to try to get the thing to turn on the none turning wheels while shes sitting on it and twists the bearings apart. After destroying 3 rollators because I didnt know what part to buy, these make it not matter. Pop out the old one, push in the new one and off we go again. As far as durability, she has destroyed one of these yet going on 8 months. So better than the original.

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 :)

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

You’re probably looking at these because they have a good price point, which they do. And that really low price point is the only reason they’re not even more lowly rated. The bearings come heavily coated with grease - enough that it actually hinders rotation. It seems like this is done because it also hides imperfections in the bearings. After clearing the bearings they rotate much more freely, but have a definite wobble to some of them. I compare them to a 20 year old set of real ABEC 7 bearings in my rollerblades and these are definitely not ABEC 7. So, if you’re looking for some bearings for a robotics project where they’re on an idler pulley, these are fine. But if you think you’re gonna drop these into a board or skates, keep looking.

Theyre basic sealed bearings from China that youre not supposed to open. They dont run fully smooth out of the container. If you work the bearing for a while, it does improve. But without disassembling and cleaning, it wont spin like a fidget spinner. Im using it for a roller on my Ender 3 printer, and for that its been fine. So just decide how smooth you need it to be. 3 of 5 stars overall.

very good for my job
