NEWS: Uploaded new version fo the bearing with improved design. Bearing-01-4mm.stl Slightly tighter grip on the rod and using one 2x6x3 mm bearing to the one closest to the mounting face, so that it doesn't build higher than the standard bearing blocks used on most printers. They use the same M3 screws as before, but uses one M2x8 mm screw for the smaller bearing. I'm using these now on my Prusa and it's smooth, quiet and completely slop free. Bearing block for 8mm shafts. Super smooth, low friction and slop free. These bearings will give you super smooth and light weight moving parts. Three of these can directly replace three LM8UU bearing blocks. They build 4mm more than the stock aluminum bearing blocks, but that's usually not a problem. Mirror the bearing in your slicer to orient it the other way if necessary. I like to use two opposing bearings on one shaft because it looks nice. Requires four 3x10x4mm ball bearings and four m3x10 mm or 12 mm screws. They can mount to the printer using the stock M4 screws.
