608 2RS Bearings, 20 Pack 608 Bearing, 8x22x7mm RS Ball Bearing Grease Seal Assembly Roller Skateboard Bearings, Double Rubber Sealed Miniature Deep Groove Ball Bearing

I'm using these bearings in a 3D printed prototype as a smooth pivot point. It's not a particularly demanding application that would require a higher performance part. It's nice to have these as a cheap component for a test article that will likely be discarded as the project development progresses.

as advertised.

I have used these on a couple of projects and they work perfectly.

Bought for 3d printing, work great!

16 of 20 bearings were fine. Four have ID ranging from 7.87 to 7.92mm. Those four will not fit on a nominal 8mm (7.99mm actual) shaft. All of the bearings seem to be well lubricated and they turn smoothly.

Gets the job done

I was expecting cheesy bearings before they arrived. They're actually very good quality. I've been using them on 3d printed files and they install perfectly, and function as expected. The oil used on the bearings is a bit on the heavy side. But with time, it should all work out nicely I think. I would buy these same bearings for the same use again without hesitation.

Using these for a heavy duty drawer project. They do not measure 22mm o.d. As the description states they are about 1mm shirt of that. Worked great for my project
