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

packed with sticky grease to make the bearings appear more precise. Once you remove the greese with a good degreaser (major effort) and replace it with a light oil you notice a lot of play in the bearings dimensionally. If your just looking for a cheap bearing that spins fast then these will do. If your using these for any projects that require some accuracy on center of bearing look elsewhere.

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!

Some bearings roll smoother than others. Most of them are pretty stiff but you can oil them for some decrease in friction. The plus is the diametric tolerances are pretty good according to my calipers. OD 22 +.04 -.04, ID 8 +.03 -.05 which is great and they work great for my low speed purposes

I purchased these to use in 3D printed components. Many reviewers commented on how they dont spin freely and some feel gritty. Bearings are made to bear a load and allow it to spin smoothly, and for this they work fine. I am using them for 3D printed projects and havent been disappointed yet. For skating I would recommend spending more and buying a set of quality skate bearings - I have a set of quality skate bearings Ive been rolling on since 2012 (~8 years now). Youll feel the low quality with every roll, I wouldnt count on these to either last as long or be anywhere near as quick and smooth as name-brand skate bearings, but theyre significantly cheaper and almost disposable while still offering a relatively frictionless roll compared to plastic-on-plastic that keeps my designs from wearing out prematurely.

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.

They pretty sticky out of the box but thats just because theyre packed with grease, a quick spray with some simple green followed by some compressed air and some oil frees them right up. You could skip all that and just blast them with WD-40 but I like to use actual bearing oil. That said, the tolerances are actually kinda terrible, they have quite a bit of slop in them and they feel rough when you spin them. I suspect thats why they over grease them, to hide the bad tolerances and low quality balls/races inside. I dont use them for anything load bearing or fast speeds, these are just used for the filament roller guides on my 3d printer.

good price, bad quality,

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.

The bearings I received were corroded (ok, they are carbon steel and not stainless) and felt greasy. Grease should not be leaking out of these things, even if they are merely shielded and not actually sealed. They were also rough to turn, as though the races and balls were badly pitted, or had dirt inside. I started to wonder if they were actually used, and salvaged from old skateboards. Thank goodness Amazon takes returns. I ended up buying a different bearing for 2x the price, still very cheap, and a much better product. Don’t waste your time with these.

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.
