HIWIN MGN12 Linear Guide Rail, 1000 mm long, is a precision miniature linear motion rail designed for smooth, accurate, and stable movement in compact systems. Made from hardened steel with precision-ground raceways, it offers high rigidity, low friction, and long service life. The 12 mm width provides greater load capacity and stability, suitable for desktop and light-industrial use. When paired with MGN12H/MGN12C blocks, it delivers quiet operation and precise positioning even under continuous use. Applications include 3D printers, CNC machines, laser engravers, robotics, and automation.

• 12 mm width miniature linear guide rail, 1000 mm length, delivered without a block
• Hardened steel with precision-ground raceways for high rigidity and low friction
• Higher load capacity and stability due to 12 mm profile; suitable for desktop and light-industrial use
• Compatible with HIWIN MGN12H and MGN12C blocks for quiet, precise motion
• Ideal for 3D printers, CNC machines, laser engravers, robotics, and automation
