BERSERKER MGN12C-2R-500 Linear Rails Viking Skis with Dual Carriages

CoreXY and high-performance 3D printer builders know that smooth, reliable linear motion is critical to print quality and repeatability — poor rails cause layer shifting, inconsistent extrusion, and mechanical wear that ruins prints and increases maintenance.

The BERSERKER MGN12C-2R-500 Linear Rails Viking Skis with Dual Carriages from West3D deliver precision motion with medium preload for consistent, butter-smooth travel. Crafted from corrosion-resistant 440C stainless steel, these rails are designed for demanding printers like the Peopoly Magneto X and Voron V2, where durability and tight tolerances matter. Dual C-type carriages provide enhanced stability and load distribution, making them ideal for CoreXY and other high-speed motion systems. These rails ship dry with grease ports for easy lubrication, ensuring long-lasting performance in humid or challenging environments.

Why Upgrade?

• Eliminates layer shifting and mechanical backlash common with low-quality rails in Voron V2 and CoreXY printers
• Medium preload prevents free-fall and ensures consistent carriage movement under load
• 440C stainless steel construction resists rust and wear, ideal for humid or workshop environments
• Dual carriages improve stability for high-speed printing and heavy gantry setups like Peopoly Magneto X
• Easy maintenance with grease ports allows long-term smooth operation and reduced downtime

Best For:

• Voron V2 builders requiring rails longer than bed size for X and Y axes
• Peopoly Magneto X users upgrading motion components for smoother prints
• CoreXY and high-speed 3D printer enthusiasts seeking durable, precise linear motion
• DIY and custom 3D printer builds needing reliable MGN12C rails with dual carriages
• Workshops in humid climates demanding corrosion-resistant linear rails

Pair With the Right Filament

Reliable motion from these linear rails ensures consistent extrusion and layer alignment, critical when printing with flexible or standard filaments.

• TPU Flexible Filament — smooth motion reduces binding and layer inconsistencies common with flexible materials
• PLA Filament — precise linear rails improve dimensional accuracy and surface finish
• PETG Filament — stable motion supports reliable printing of tougher, more temperature-resistant filaments
