Customer Reviews (4.8 / 5 · 5 reviews)

Mia ★★★★★

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.

Emma V. ★★★★★

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.

Riley F. ★★★★★

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.
