8 stuks LM8UU-lager, 3D-printer massief polymeer glijlager 8 mm as lineair lager, plastic lager voor 3D-printer

I'm amazed by how quiet these make my y-axis. At first glance, I thought they were too small, but they are perfect, they fit tight and perform amazingly. Price wise, they are excellent, and a doddle to fit, I'll buy more from this seller and upgrade the rest of my printer.

OD is 16mm instead of the 15mm that you'd find in LM8UU bushings, but that is all but forgotten by me when compared with how poorly manufactured they are.I can forgive seams in an injection-molded product but the machine used to make them must have been held together with duct tape, as they show almost no consistency between one to the next.I could not find any two bearings together that approached anything remotely resembling concentric, so use in a printer is generally an awful experience.

not standard sized outer diameter, internal yes 8mm but these don't fit a standard LM8UU housing so crap really.

Wrong size! Outer diameter is bigger than advertised. Had to buy again from other seller
