Premium 350mm Stainless MGN12 Linear Rail Kit with Carriage
✔️ 350 mm rail length, MGN12H carriage, 4-M3 holes, 25 mm spacing

This precision stainless steel linear rail and MGN12H carriage are built for smooth, high-precision motion in 3D printers, CNC machines, laser cutters, and other automated setups. Rail length is 350 mm (13.78 in) and the carriage block measures 45.7 x 27 x 10 mm (1.80 x 1.06 x 0.39 in). Made from 440C stainless steel, it offers higher hardness and corrosion resistance than standard bearing steel. The carriage features four M3 threaded holes (4-M3x3.5) with a 20x20 mm center spacing; rail holes are spaced every 25 mm along the length. Two rubber stoppers at the ends prevent derailment.
