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

Im not sure if its the batch I got and the heat melted the plastic (doubtful being in Northeast), but these are okay. It was very sticky and barely spun, but after letting them soak in a couple sprays of T-9, they were spinning... but not spinning the way Id expect bearings to, but the minimum amount. I purchased these for my Powermatic PWBS-14 Bandsaw, and they fit and match for a fraction of the cost from buying them directly from Powermatic. If purchasing again, Id try another company.

Used to replace bearings in a rollator walker.

Pretty stiff and sticky out of the tube. A little wd-40 to clean them you and loosen them and they work just fine.

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

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

Clean these bearing out with acetone or similar solvent and they will work pretty good. My uses are under low Load, toys or low rpm applications so I can not comment on high load applications. The 5 star rating is my rating of these performance vs the price. If you are expecting high precision bearing you will need to spend more per bearing.

They seem loose and wobbly and many of the shields protecting the bearings from dirt are dinged up like they were installed by hand by someone in a hurry. A bearing should only spin and not move in other directions. I plan to use them for wheels on parts bins, so theyll work for that, but I wouldnt bother with them again.

I bought these to use for 3D prints instead of skateboarding, so my review doesnt necessarily reflect their intended use. Ive noticed for about half of these bearings, they tend to bind up and stop spinning at lower speeds. And they dont come with any greese or oil in them as far as I can tell. Ive sprayed silicone lubricant in them and that seems to make some of them work better, but most of the problem bearings still bind up at low speeds. They all function, but if you want extremely smooth and reliable bearings, Id suggest you look somewhere else. They functioned just fine for my project, but I think the quality control could be better.

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.

Currently using one as part of a 3D printed stabilizer for my Z-axis on my Ender 3. Its the perfect fit allows rotation and little wobble. Printing has been going a bit faster and cleaner.
