- 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

Sold as a pair, one was the correct 20mm, the other measured 19.2mm which is very sloppy on a 20mm rail with no means to adjust. Obviously poor ( if any ) quality control...Amazon makes it easy to return but what a pain/delay having to return just to roll the dice again hoping I can complete the project...

Slightly tighter than advertised. Have to be a critical factor to make a difference.

I wouldn't do it again. Bearings sit out of square with the base . I seem to recall them feeling cheaply made. They were replaced fairly quickly. But I'm not upset about it. I got what I paid for.Side note: Please do Reviews here on Amazon. Honestly ones, Good, Bad or Indifferent. Our honest feed back helps others decide what to spend money on.Thank you
