There is an apparent reason why the balls are not round, but square. The one out of four is, well, somewhat acceptable. One would think that after the rod is rubbed with grooves, it will run My oily housings seem to completely disregard the lubricant, even though I packed plenty of grease into them. Only the rod mounts can be considered a negative since they are very well designed, yet if used with a 3D printer the build plate carrier may be too low and hit the mounts during The fact that these things are called slide bearings is a mystery to me. This motion can't be registered because it is absolutely smooth. There is no comparison between brass and aluminum bushings. In applications where smooth operation is required, they will cause problems due to their binding at certain points on the rods. It is hard for me to imagine exactly what my 3D printer will sound like, but possibly like a freight train, even though I have not installed them yet. It's only once you purchase that you will find out about these things. Announcing an update A test bed has been set up to run those programs. My bench had two or three pieces of metal on it after I moved it from one end to the other two or three times. Actually these are two ball bearings from incredibly smooth, durable, and smooth operating slide bearings that fall apart even before they are installed in.

It's a good idea. There is no lag in their operation. I appreciate it.
