2-Pack Linear Motion Rods - 20mm X 400mm Chrome Plated Steel Shafts For CNC & 3D Printers | Super Smooth & Straight!
About this item
Hey there!
Need a smooth, sturdy rod for your CNC machine or 3D printer setup?
Check out this pair of linear motion shafts.
They're made from high-quality C45 carbon steel, hardened to 58-64 HRC for serious durability.
Each rod is 20mm in diameter and 400mm long (that's about 15.75 inches), with a shiny chrome-plated finish that's not just for looks—it resists corrosion and wear.
The surface is super smooth (Ra 0.8 finish), and straightness is super precise (under 5μm per 100mm).
Both ends are chamfered so they won't scratch your bearings or your fingers during install.
Want a custom length or threaded ends?
Just message us—we can make them pretty much any way you need.
We also stock other diameters like 5mm, 8mm, 10mm, 12mm, 16mm, 25mm, 30mm, and up to 50mm.
Perfect for DIY builds, machine upgrades, or prototyping.
These rods are tough, accurate, and ready to slide into your project.
Get yours and make your motion system buttery smooth!
