This 100cm chrome-plated smooth rod (12mm diameter) is ideal for linear motion applications. With high-frequency induction hardening and corrosion resistance, it's perfect for 3D printers, CNC machines, and robotics requiring strength, accuracy, and smooth operation.
The 12mm Diameter Chrome-Plated Smooth Rod (100cm Length) is a high-precision linear shaft designed for 3D printers, CNC machinery, linear stages, and automation systems. Manufactured from hardened steel and coated with a chrome finish, this rod provides excellent wear resistance, anti-corrosion properties, and low friction operation.
The rod undergoes high-frequency induction hardening, increasing surface hardness for extended durability and smoother motion. It is precisely ground and polished to maintain tight diameter tolerance—ensuring optimal compatibility with linear bearings (e.g., LM12UU) and other motion components.
