2pcs MGN12H 400mm Linear Rail Kit for 3D Printer and CNC Machine

Packing list:

• 2 MGN12 linear rails
• 2 MGN12H carriage blocks

The spacing of each hole on the rails is 25mm, with varying numbers of holes for different lengths: 200mm (8 holes), 250mm (10 holes), 300mm (12 holes), 350mm (14 holes), 400mm (16 holes), 450mm (18 holes), 500mm (20 holes), 550mm (22 holes).

Difference between MGN12H block and MGN12C block: - MGN12H: Long Carriage Block, size 45.4mm x 27mm x 10mm - MGN12C: Short Carriage Block, size 34.7mm x 27mm x 10mm

Please choose the correct size and type you need.

Installation and usage advice: 1. Before installation, lubricate the rail and slider. 2. Avoid removing the block during rail installation unless necessary. 3. Do not arbitrarily switch the block of the rail during installation to maintain accuracy. 4. Regular lubrication is recommended to reduce friction, prevent burns, minimize wear, and extend service life.

【Easy to install】 Standard MGN12 linear rail, 12mm width, 8mm thickness, with pre-drilled ⌀3.5mm mounting holes. Metric mount holes with 25mm spacing. Use M3*8mm bolts and T nuts for installation.

【High Quality Material】 Crafted from durable stainless steel, the linear rail offers strong rigidity, high precision, and rust resistance. Its four-point contact design provides multi-directional load-bearing capabilities.

【Smooth and Quiet】 After lubrication, the rails effortlessly pass a free-fall test at 45°, ensuring smooth movement with minimal noise and binding. Superior quality and workmanship contribute to a long service life compared to other brands.

【Wide application】 These compact and lightweight linear guides are ideal for miniaturized equipment like routers, 3D printers, and plasma cutters.

【Outstanding service】 For any issues with your product, contact us for assistance. If damage occurs during use, we will provide a replacement. Thank you.
