In high-performance linear motion systems, the foundation determines precision and durability. At Hanli, we specialize in the R&D and manufacturing of Stainless Steel Rail Track Bars, providing high-precision, customizable Linear Guide Rail Substrates for global customers in automation, machinery, automotive, and precision equipment industries.
As a direct manufacturing enterprise integrating R&D and production, we deliver reliable, cost-effective rail substrate solutions with full technical traceability and international quality certification.
Premium Stainless Steel Materials – Built for Performance
Our Stainless Steel Rail Track Bars are manufactured using high-grade stainless steels, including:
95Cr18 Stainless Steel
X65Cr15 Stainless Steel (jointly developed with Qingshan Steel)
Among them, X65Cr15 offers optimized performance for linear guide applications, combining hardness, wear resistance, and structural stability.
Material Advantages
Compared with standard market materials, our rail track bars feature enhanced alloy composition:
Cr (Chromium) – Improves oxidation resistance and corrosion resistance
Mo (Molybdenum) – Refines grain structure, enhances hardenability, and improves thermal strength
This ensures:
✔ Excellent wear resistance
✔ High load-bearing stability
✔ Extended service life
✔ Superior machining performance
Our stainless Steel Rail Track Bars provide the ideal base material for precision guide rail systems.
Comprehensive Specifications – Standard & Wide Series
We offer a full range of linear guide rail substrate specifications:
Standard Series
N2, N3, N5, N7, N9, N12, N15
Wide Series
NW2, NW3, NW5, NW7, NW9, NW12, NW15
This wide coverage allows compatibility with various guide rail structures and application scenarios.
Example:
N9 groove depth: 1.12mm
Other groove depths available upon request
We ensure precise structural matching for different linear motion systems.
High Dimensional Accuracy – Strict Tolerance Control
Precision is the core of high-performance Stainless Steel Rail Track Bars.
