I bought a lot of these cariages to build cnc. They need a little bit of tuning to move smoothly. If you buy a complet, linear rail and carriage, they will work probably good. Due to a small differences in widths between various rails and a various diameters of balls, they can struggle a little bit. But you can find a lot of videos on youtube how to improve them. Original balls diameter is 2,381mm, but I found them in range of 2,36 to 2,42mm. Anyway, the body looks good so if you devote a little bit of effort they will run smoothly

got it but haven't tried it yet. hope it works better than other types of linear rails.

This type of linear bearing should be better than those round linear bearings. Will see that when I get to that point.
