Smooth rod( Chromed Hardened Shaft)

Smooth Rod (SS) — Chromed Hardened Shaft, Linear Motion

Precision-ground smooth (unthreaded) rods made of chrome-plated high-carbon steel, designed for smooth, low-friction linear motion. Used with linear bearings and bushings across 3D printers, CNC machines, robotics, and general motion-control builds. Available in multiple diameters and lengths to fit your exact project needs — select the combination you need below.

Product Details

Diameter Tolerance, Hardness & Weight (per metre)

Features

• High precision, high hardness, high dimensional stability
• Precision ground surface for smooth, low-friction linear travel
• Chrome-plated finish resists wear, scratching, and corrosion
• Compatible with standard linear bearings and bushings matching each diameter (e.g., LM4UU, LM8UU, LM12UU)
• Consistent diameter tolerance (g6 grade) across the full rod length

Applications

• 3D printer X/Y/Z axis guide rods
• CNC and engraving machine linear axes
• Robotics arms and sliding mechanisms
• General motion control and automation projects
