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

Delivery is quick, as expected from Amazon. When I opened the bearings there was a rancid smell that came from the bearings. That indicates that the grease has run pass it life. When I try to spin the bearing it was not smooth. When I touch the bearing, there was a sticky feel to it. I may have gotten the old bearing instead of their newer ones.

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!

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 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.

I had to make a bass string winding machine for musical insterments and these bearings are just what I needed. In the pass bearings like these were in windmills, worleyjiggs I think its what they are called forgive my spelling! Since you cant find them in local stores you have to depend on reviews like these. YES I WILL USE THEM AGAIN. Good luck!

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.

The dimensions are WAY off. Pressing these in was more like dropping a toothpick into a volcano. Luckily i dont need a press fit for my application, so it didnt matter. You really get what you pay for here. Also the race was PACKED with FOD. So much aluminum or steel glitter is packed in with the bearings, it feels like sand when you move the bearing around. Only two out of the pack where smooth. This is real bottom of the barrel stuff, but its also literally the cheapest i could find. Im pretty sure the oil that was covering them was some kind of caustic nonsense and it made my skin red where it touched me.

Purchased these for use with my 3D printer, filament spool attachments. These worked great. Nicely sealed, lightly oiled and in a nice reusable container.
