With years of experience in manufacturing linear shafts, we provide customer satisfaction through manufacturing and customization.
At Bos, we care about you and your company. We specialize in the customization, material selection, and manufacturing of linear shafts, and provide excellent services according to your needs.




Choosing our Linear Shaft Rods translates directly into enhanced machine performance and reduced total cost of ownership. The primary advantage is their exceptional wear resistance and longevity, achieved through induction hardening and hard chrome plating. This creates a extremely durable surface that withstands constant friction from bearings, significantly extending the service interval . Secondly, our rods offer superior dimensional accuracy and geometric precision. With tight diameter tolerances (e.g., ISOf7, g6), excellent straightness (e.g., ≤ 0.2/1000), and controlled roundness, they ensure smooth, stick-slip-free motion, minimal vibration, and high positional accuracy, which is crucial for precision manufacturing .
The high-strength core material provides excellent load-bearing capacity and resistance to bending, ensuring stable performance even under significant radial loads. Additionally, the mirror-like surface finish not only reduces friction and wear but also protects against corrosion, enhancing the rod's suitability for use in clean rooms or environments with moderate levels of humidity and contaminants . For applications requiring lightweight components or internal routing of wires and cables, our hollow Linear Shaft Rod variants offer a perfect solution without a substantial compromise on strength.


Selecting us as your Linear Shaft Rod supplier means entering a partnership grounded in technical expertise and a commitment to quality. Our vertical integration and in-house manufacturing control allow us to maintain consistent quality from raw material to finished product. We offer an unparalleled level of customization, providing rods in a wide range of diameters, from 6mm to 500mm, and lengths up to 16 meters, with various end-stage machining options such as external threading, internal threading, and wrench flats to meet your specific assembly requirements . Our technical team possesses deep knowledge of material science and tribology, enabling us to provide expert guidance on selecting the optimal rod specification—be it a standard chrome-plated rod, a stainless steel version for enhanced corrosion resistance, or a hollow design for weight reduction. We are more than a component supplier; we are a solutions provider dedicated to optimizing your design.

The most common materials are high-carbon chromium steel (like SUJ2/52100), which is hardened and chrome-plated for optimal wear resistance. For corrosive environments, stainless steel (such as SUS304 or 440C) is used, offering excellent corrosion resistance though with generally lower hardness than hardened steel.
These are international tolerance grades for shafts. A grade like g6 indicates a sliding fit, perfect for applications requiring precise movement with minimal play. h6 is a precision location fit, offering very tight tolerances for high-accuracy systems. The choice depends on your required balance of freedom of movement and positional accuracy.
