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

Product is as described

I am not using them as they are intended to be used. I am over speeding the bearings. But they are holding up

I bought these to use for some 3D prints. They are skateboard bearings, so they come pre-greased. I would have preferred to have non-greased bearings, but it makes sense that they would be greased.

Good bearings. I have used these in a variety of 3D printed projects. They exhibit a little more friction compared to the bearings found in fidget spinners, but they will last much longer I am sure.

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

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

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.

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.

I did not use these in a skating application. I can not speak to their durability in that application. There were used in a spooler that required a set of 608 bearings that could simply roll smoothly at low speeds. All dimensions were within stated specs for 608 bearings. They come pre-greased in tubes of 10. No complaints and would order more for additional projects.

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.
