The KHS-LG ST 20mm Linear Motion Shafts with Support system is engineered for reliable and precise linear guiding in demanding industrial environments. The combination of a high-quality C45 steel rod and a rigid aluminum support base (ST series) provides superior strength and stability compared to unsupported round shafts, making them suitable for high-load, high-accuracy applications.
Key Features and Specifications:
Material (C45 Steel): The shaft itself is crafted from C45 medium carbon steel, known for a balance of strength and machinability. After hardening and grinding, it achieves a surface hardness of 58-62 HRC and a hard chrome plating thickness of 0.01-0.05 mm for enhanced wear and rust resistance.
Dimensions: Designed for a nominal 20mm shaft diameter, with specific dimensions for the support base to ensure standardized fit and installation.
Integrated Support: The continuous aluminum support rail eliminates shaft sag or deflection, a critical factor for maintaining accuracy over long spans and under heavy loads in dynamic drive applications.
Performance: The system is optimized for use with linear ball bushings, enabling smooth motion, low noise, and high-precision positioning required for industrial automation equipment.
Installation: The aluminum support base is pre-drilled with mounting holes, allowing for easy and secure installation onto machine frames using standard M6 screws.
This linear motion system provides a durable and accurate foundation for machinery requiring repetitive and precise straight-line movement.

C45 Steel ST 20mm Linear Motion Shafts with Support By KHS- LG
The KHS-LG ST 20mm Linear Motion Shafts with Support feature a robust 20mm diameter C45 steel shaft mounted on a continuous aluminum alloy support base. The C45 steel shaft is precision ground, case-hardened (to 58-62 HRC), and chrome-plated, offering excellent wear and corrosion resistance. This fully supported design prevents deflection under heavy loads, ensuring smooth, high-precision linear travel when used with compatible SBR20UU bearing blocks in applications like CNC routers and automated machinery.
