### ⭐⭐⭐⭐⭐ Fattening sled

Slides very smooth and works perfectly.

### ⭐⭐⭐⭐⭐ Linear rails and bearings
*by A***D on January 16, 2026*

Installed these rails on my concrete plasma machine and so far they work s long as you make sure that no debris get into the bearings.

### ⭐⭐⭐⭐ Great rails but with just a little bit of flex
*by L***X on July 28, 2022*

Great rails but with just a little bit of flex. I used these for a router sled. There were two drawbacks. The first was hunting for the correct screw size of the holes on the mounting blocks. (Metric6 by the way) The second if a little bit of flex in the rails. For a full size router I may have to go back and add some steel underneath the rails so they don't sag.
