Linear Optical Axis

Product Overview

Linear optical shafts, also known as linear guide rollers, are core linear motion components for industrial automation and precision machinery. The product series includes solid shaft, hollow shaft, hard chrome-plated shaft and tempered soft shaft. Manufactured with high-quality 45# steel, 40Cr alloy steel or stainless steel, processed by precision centerless grinding, high-frequency quenching and mirror chrome plating, it serves as a standard guide part matched with linear bearings, slide blocks and shaft supports.

This linear guide roller features precise roundness, ultra-low straightness error and high surface finish with low friction coefficient, realizing stable, accurate and quiet reciprocating linear motion for mechanical equipment. The hard chrome-plated surface reaches hardness above HRC 60, delivering excellent wear resistance, rust proof, corrosion resistance and anti-deformation performance, suitable for long-term operation in dusty, humid and high-frequency industrial environments.

Complete size coverage from Φ6mm to Φ80mm with customizable lengths for universal compatibility. Widely applied in CNC machines, laser equipment, 3D printers, automation production lines, packaging & printing machinery and intelligent robots. As an essential part of precision linear transmission systems, it greatly improves equipment positioning accuracy and operational stability.
