I got these to replace the linear bearings on my Creality Ender 3 V3 SE printer since the original ones had a lot of play in them causing issues with bed movement. These fixed all the issues!

I bought these for a 3D printer re-build I am doing. Fuishi and Fluishi (the other budget bearing brand on Amazon) are much better. The uxcell come bone dry from the factory, completely ungreased. I got one of them to work, passably, because I had a specific LM8UU grease applicator tool and soaked another in machine oil overnight. But there was a lot of catching/grinding with the smooth rod. Waste of money.

Purchased these to replace the z axis bearings on my 3018 cnc. These are almost three times longer but appears to have much more play on them. The inner black part of the bearing actually moves inside the outside casing.

Good value upgrade for my i3 mega bed bearings! Exactly what I needed. Thanks!

They are a bit scratchy as far as audible noise and there is some slop on a 8mm hardened rod. This is my first set of linear bearings so I don't really have any reference point but they work pretty well 👌 would buy again.
