9mm Linear Guide MGN9 system with rail and compatible blocks offers precise, smooth linear motion for compact CNC and 3D printing applications. This setup pairs an MGN9 9 mm rail with either an MGN9H or MGN9C block, and is available in a range of lengths to fit your build. Key features and benefits Precise 9 mm linear guidance: MGN9 rail paired with a matching block provides reliable, lowfriction motion for moving parts. Flexible length options: Available in 100, 150, 200, 250, 300, 350, 400, 450, 500, 600, 800, and 1000 mm lengths to suit different axis spans. Block compatibility: Comes with either an MGN9H or MGN9C block, enabling compatibility with established MGN9 accessories and setups. Versatile for small and mid‑size systems: Well suited for 3D printers, CNC routers, laser cutters, and other CNC machinery requiring precise linear travel. Easy integration: Standard rail and block form factor simplifies mounting to frames, gantries, and carriage assemblies. Product attributes Rail type: 9 mm linear guide rail (MGN9) Block options: MGN9H or MGN9C Available lengths: 100, 150, 200, 250, 300, 350, 400, 450, 500, 600, 800, 1000 mm Applications: 3D printers, CNC routers, laser cutters, milling machines, automated equipment Suitability: Suitable for systems that require reliable linear motion with a 9 mm guide Variants and note MGN9C, 600 mm variant is available as part of the lineup, alongside other lengths with either MGN9H or MGN9C blocks. Use cases 3D printer upgrade or build: Use the 9 mm rail with an MGN9H or MGN9C block to improve axis stability and print quality on X or Y axes, or for a robust Zaxis assembly. CNC router or milling machine gantry: Implement the rail and block to achieve smooth, repeatable motion for a compact gantry or carriage system. Laser cutter or precision automation: Integrate into a moving carriage or table to enable precise, repeatable linear travel for cutting, engraving, or pickandplace tasks. Installation considerations Ensure rail length matches the axis span and that mounting holes align with the frame. Confirm block type compatibility with existing accessories and mounting patterns. Align the rail and block precisely to minimize runout and maximize straightness during operation.
