2PCS Linear Motion Rod, 20 mm x 1200 mm (0.79 x 47.24 in), SFC20 Carbon Steel Linear Rod Shaft, Anti Rust and High Precision, High Hardness Shaft, for Cutting Grinding Milling Drilling Machine

• 2-Piece Linear Motion Rods: This set includes two 20 mm diameter, 1200 mm long linear rail shafts. The high-compatibility design pairs seamlessly with various linear rails and machinery, ensuring smooth and stable motion for industrial applications
• Hardened Carbon Steel Shaft: Crafted from carbon steel with a hardness of HRC58–66, the linear guide rail shaft delivers exceptional strength and resists bending under heavy-duty use, maintaining consistent accuracy in automation and mechanical systems
• Rust & Corrosion Protection: The linear motion rod shaft surface is coated with a ≥10 μm electroplated layer to resist corrosion and rust, making it suitable for long-term use even in damp environments like basements
• High-Precision Linear Motion: Manufactured using a six-step grinding process, the guide rail shaft achieves a 0.1–0.22 μm surface finish and a 5 mΩ straightness, delivering reliable, repeatable travel over time
• Widely Compatible Applications: Ideal for DIY CNC mills, lathes, bending machines, laser welding machines, and other automated equipment. These linear rod shafts are also fit for large industrial systems like robotic arms and wire drawing machines
