- Linear motion bearings provide freedom of movement in a single direction.
- Often used in conjunction with cylindrical shaft or rail.
- The steel ball is in point contact with the shaft and rotates with very little frictional resistance, so as to obtain smooth movement with high precision.
Linear Ball Bearing Motion Slide Units
- Grease may be applied prior to use to improve smoothness.
- Maintain lubrication of optical shafts and guides during operation.
- The recommended load is 80% of the rated load, exceeding the rated load will affect fluidity.
- The table needs to be level during installation, otherwise it will interfere with installation calibration.
- Require regular cleaning and maintenance.
Linear Motion Bearing
X-Y tables, linear stages, machine slides and other advanced slides use linear motion bearings to provide movement along both X and Y multiple axis.
Applications
- Replacement of parts of the 3D printer rail unit.
- Replacement of common machine tool guideway components.
- Laser (engraving machine) rail set-up and parts replacement
- Construction and replacement of small planing machine tables, carriers, rails and parts.
- Mechanical Slides
- 2-axis, 3-axis Benches
- Linear Stages

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.

Had one completely screw up and ruined my 10mm smooth rod.

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.

Shows falsely in 10mm bearing section.To make sure, this review is for the uxcell LM8UU Extra Long Linear Ball Bearings.Received Item on time and went to install. Put some lube into the bearing and installed it.During the first test, the inner works came out to say hello and spilled the tiny balls all over.Check the images and you'll understand what I am saying.This was within the first few seconds after install, not after 2000 miles or so.So, there must be no QA or very little of it.I don't feel like going through the return process, since the cost of it doesn't justify this action.

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.
