جلبة محمل نحاسية ملبد 8×12 مم، أطوال 15 / 22 / 30 مم

The 30mm ones pressed into my linear bearing block with zero play, and the sintered copper surface feels buttery-smooth when the shaft runs through it. Even after a few days of constant printing, I can’t feel any wear or roughness creeping in.

The 22mm length slid perfectly onto my Prusa i3's Z-axis rod—no binding at all. After a week of printing, the motion feels noticeably smoother than with the old plastic bushings. Definitely a solid upgrade for anyone running linear rods on their printer.

Pulled the 30mm length for my linear rod supports and they slide much quieter than the old plastic bushings. The oil-impregnated copper material is a nice upgrade for smooth motion.
