Not sure if they are original or fake. Binds like crazy.
I used this for Z axis of my CoreXY 3d printer (custom built).I have made sure the linear rods are perfectly parallel. These bearings move fine before I install the print bed with heater, glass plate etc., Once there is cantilevered load on it, it does not slide smoothly. Binds like crazy. I do understand these are supposed to be "self-lubricating" meaning, they slide without needing oil or grease. But, not so in my case. I removed them and installed several times and made sure rods are parallel etc., disappointed.If anyone is looking at these for z axis, I recommend long, one piece linear bearings (LM12LUU) with a flange like those used in a Creality Ender or Sainsmart printers.

Great bushings
These do a great job. Slide smooth, little to no play. 12mm ends up being a great deal stiffer than the “standard” 8mm for printers

Great Producet to reduce noise and vibration
Very quiet and still just as accurate!
