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
