DollaTek 4 stuks LM12UU 12 mm binnendiameter, rubber, verzegelde lineaire kogellagerbus voor 12 mm stang, CNC-onderdelen, sferische glijlagers

fatto breve test scorrendo a mano, sembra tutto ok

Received them for use with my 12mm steel rod. They were a little loud but as it is used on the Z axis on my 3d printer that wasn't an issue. 2 of them worked flawless, one was a little tight but still worked as intended while the 4th one had seemed to leak out all its oil and would seize up during movement (will try applying some lithium grease or other lubricant so see if it fixes the issue. Not sure if it was just an unlucky purchase but for now ill be using a 3d printed bearing with some PTFE oil as a replacement if grease does not help out.

Installé sur une imprimante core x, ils sont parfait et je conseille. L'utilisation de ces roulement est convaincante et très fonctionnelle. On sent tout de même un peut d'accroche mais peut être en y mettant une peut de graisse lithium, cela peut s'arranger

bueno

Tutto bene
