• What You Get: 2PCS 12mm x 500mm Linear Motion Rods Set
• Premium 45# Carbon Steel Construction: Crafted from durable 45# carbon steel and hardened to HRC55-62, these linear shafts resist wear, deformation, and corrosion. Perfect for heavy-duty CNC machining, high-speed 3D printing, and repetitive industrial automation tasks
• Ultra-Smooth Chrome Plating & Precision Finish: Features a 0.01mm chrome-plated layer and Ra0.05-0.08 surface roughness for frictionless motion, reduced noise, and extended lifespan—ideal for precision-driven applications like laser engravers, robotic arms, and linear guide systems
• Engineered for Flawless Accuracy: Strict diameter tolerance (-0.01 to -0.03mm) and ≤0.1/1000mm straightness ensure seamless compatibility with bearings and pulleys. Achieve micron-level precision in CNC milling, automated packaging, or custom DIY builds
• Multi-Industrial Versatility: Beyond 3D printers and CNC routers, these rods excel in robotics, textile machinery, medical devices, and lab equipment. Upgrade your workshop, prototyping studio, or small-scale production line with reliability
