The Review of: 7/9/12/15mm Linear Guide MGN7/9/12 100 150 200 250 300 350 400 450 500 550 600 650 700 750 800mm+MGN12H MGN12C Block 3D Printer Review

Let’s delve into the world of linear guides and their applications in 3D printing and other precision machinery. Linear guides play a crucial role in ensuring smooth and accurate motion along a linear path. Here’s what I can share based on the information you provided:

  1. MGN Series Miniature Linear Guideway:

    • These tiny and lightweight linear guides are specifically designed for miniature equipment.
    • Key Features:
      • Made from a special grade of stainless steel to prevent corrosion.
      • Gothic arch contact design provides high rigidity and accuracy.
      • Steel balls are held by a miniature retainer to prevent them from falling out during block removal.
      • Available in both non-interchangeable and interchangeable types.
    • Construction:
      • Components include the block, rail, end cap, and retainer.
      • Lubrication via a grease nipple (available for MGN15).
      • Dust protection with end seals and bottom seals (optional for sizes 9, 12, and 15).
    • Applications:
      • Semiconductor equipment, PCB/IC machinery, robotics, measuring devices, and other miniature sliding systems.
    • Model Number Example: MGN12H (Reinforced Cap) .
  2. MGW Series Wide Type Miniature Guideway:

    • Enlarged width for increased moment load capacity.
    • Gothic arch contact design ensures high rigidity in all directions.
    • Stainless steel components for anti-corrosion properties.
    • Similar construction to MGN series.
    • Available in both non-interchangeable and interchangeable types.
    • Model Number Example: MGW12C (Interchangeable Block) .
  3. Dimensions:

    • The specified lengths (e.g., 100mm, 150mm, etc.) refer to the rail length.
    • Tolerance of the E value (rail length) varies based on standard or jointed rails.
    • Maximum standard length indicates the maximum rail length with standard E value on both sides.
    • If you need smaller E values, consider contacting the manufacturer .
