Hi
I purchased a no name 80x160mm extrusion, I mounted profile linear rails to it but the extrusion was warped and the linear rails lean into each other slightly, and it locks up and the bearings don't move properly so I am looking at a different extrusion now so I am wondering if the 8020 is better for mounting 25 series hiwin linear rail, I am looking at the 80x160mm or the 3x6in extrusion. Any info and help would be fantastic.
Thanks
Chris
