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

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!

Kind of trash and hardly worked. Almost all failed with a roll pin installed.

works in a lot of prints for 3d printers. i used to add to prints for a mount for the filament spools and a filament feed guide. greatly reduces tugging and grabbing and i have plenty of extras!

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.

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

I got the bearing to use for the 3d print parts, but out of the box the bearing does not rotate too well. You may need some clean up and re lubricant depends on the use. Overall its OK for basic use.

Picked this up for a spool holder and they worked great! Had to spray down with some WD-40 and roll a bit but once that was done they worked great. Have a few more filament guides Ill print that will use this but great for what they needed to do.

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 are labeled as 608ZZ and are double metal shielded. The ability to spin freely is somewhat limited for some reason. I dont know if the grease inside is too thick or what, but if youre looking for a bearing for a fidget spinner then you might want to look elsewhere. On the other hand, there is no play between the inner race and the balls and outer race, so I cant say they are sloppy loose either. I think they are a god value for the cost as long as you are not wanting something that is going to spin freely for any length of time.
