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

If you have 608 bearings for guides these are great and priced right. You can replace every year for a very cheap investment.

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

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.

Was swapping these into a 1/5 rc car and out of the 20 I was lucky to get 6 that werent gritty. Well see how long they last but next time Ill spend a bit more and get some from a company that has some better tolerances. After blowing out the grease and re-lubeing they got a bit better but still not as smooth as I am used to. Plus side, they dont chirp but thats about it. Update - 7/31/21 - They chirp. Got gritty quick and not smooth. Look elsewhere.

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.

Great product for the money spent

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.

Pros: - Cheap - Comes with shipping oil to keep out any grit/grime Cons: - The QC is awful I purchased two packs of these to use for a project and found that 10 of the 40 bearings had issues. Many were minor such as small dents/dings in the shields, but there were a few where the entire inner or outer bearing piece has been chewed to bits. If youre going to buy these, make sure you buy extras since about a quarter of them might be faulty. Since this was fulfilled by Amazon, Im unable to contact the seller for replacements and dont want to return the rest. Still three stars though, you get what you pay for.

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

Had to clean with WD-40 but after that they all spun freely no problem
