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

Used with 3d printing projects. Sizing seems accurate, and rotating action seems smooth with low friction. Looking forward to finding more uses and buying again, cause its FUN making stuff

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

They seem to be gritty when turned.

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

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.

These are nice bearings, but despite the positive feedback, DO NOT use these for fidgets. I bought these so I could 3D print some spinners and resell them but these were just spinning disappointments. I gave 4 stars because this is advertised for skating, not fidgeting.

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 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!

This is a very high quality bearing. As others have stated, its got a good thick lubrication applied. Out of the box, they are perfect for heavy loads. For most tinkering and crafting where you want as little friction/resistance as possible, youd probably want to heat these a little and get rid of that lube to install a lighter weight lubrication. Other bearings might spin better out of the box, but the quality will probably be lower. Id recommend these bearings.

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!
