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

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 :)

Came quickly and just ad described, durability is something Ive have to see. Size aas correct as well.

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 seem to be gritty when turned.

Bought these for a filiment guide i was printing. 4 stars only because they arent high end bearing but they are excellent value and come in 2 plastic tubes for storage. Must have for 3d prints

Purchased a set of these bearings for 3D print related projects that require 608 bearings. All of my applications would never put real stresses on these bearings as a skate would, so I cannot review this as its official intended purpose. For my purpose, I have zero issues. So far, I have printed out a filament spool holder and a filament guide. The bearings are smooth. With the set I received, do not have any issues with them being too stiff or too slick as far as ease to roll.

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.

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.

Guys just go to the skate shop. Ik you are looking for a cheaper way to skate, its not worth it. Buy REDZ if you have to but dont do Amazon skate stuff you will regret it. These were very loud, and you didnt get very far skating, but its enough to get you by.

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.
