Z AXIS SLIDE ASSEMBLY:

There is a process that I call “marrying” the linear bearings (LM6UU-M or LM6UU-3D) to the smooth rod (S6MM). The process
involves taking each linear bearing one a time and finding out which rod it slides best on. This helps to minimize the amount of
binds. Please note that linear bearings (LM6UU-M or LM6UU-3D) travel along the length of the smooth rod while radial
bearings (608ZZ) ride around the smooth rod.



Select a linear bearing ((LM6UU-M or LM6UU-3D)) and place it a polished and lubricated smooth rod (S66M).



Move the linear bearing (LM6UU-M or LM6UU-3D) back and forth along the length of the smooth rod (S6MM).



If the linear bearing (LM6UU-M or LM6UU-3D) binds, try another one until you find the best match.
