I have used these in a machine I am building similar to how they would be used in a 3D printer. The fit is perfect, the material is durable and the linear movement is absolutely fluid. They are designed (I think) for 2020 aluminum extrusions, but I've used them on 2525 extrusions and they still work great to this day.
