Precision linear motion with MGN12 guide
The 12mm MGN12 linear guide rail provides smooth, precise linear movement essential for 3D printers and CNC machines. Crafted from durable GCR bearing steel, it offers excellent corrosion resistance and high temperature tolerance, ensuring reliable long-term performance.
Each rail is available in lengths from 100mm up to 1000mm and can be custom cut to suit specific project requirements.
Carriage blocks for smooth operation
Choose from the MGN12H or MGN12C carriage blocks for your linear guide assembly. These black blocks integrate with the rail to enable light preload linear motion, helping reduce vibration and play.
- MGN12H and MGN12C block types available
- Light preload for smooth sliding (default Z0)
- Ideal for 3D printers and CNC machines
High-quality materials and construction
The guide rails and blocks are made from high-grade GCR bearing steel, which resists rust and corrosion while maintaining strength under high temperatures. This construction supports durability even in demanding industrial environments.
- GCR bearing steel for corrosion and rust resistance
- High temperature durability
- Precision manufacturing for reliable accuracy
Customizable and easy to maintain
Rails can be cut to customer specifications to perfectly fit your machinery. If initial carriage movement is stiff, pressing the carriage and adding lubricant will improve fluency for optimal performance.

Sometimes cart gets stuck a little, even after i removed transport coating and relubricated it. came with spare bearing balls.
It doesn't slide on my rail at all, it's difficult to get it in, and it moves very slowly.
Ok
ok, as described
