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.




Our Stainless Steel Shafts are designed to offer a combination of benefits that set them apart in the competitive landscape. First and foremost is their exceptional corrosion resistance, which ensures longevity in humid, saline, or chemically exposed settings. This is complemented by high tensile strength and durability, achieved through tailored heat treatment processes such as quenching and tempering, which optimize the microstructure of the material for enhanced load-bearing capacity and impact resistance. Additionally, our shafts exhibit superior surface quality, with finishes achievable to tolerances as tight as Rz 0.4 µm, reducing friction and wear on seals and bearings. Finally, their lightweight design (particularly in hollow configurations) minimizes inertia in rotating systems, contributing to energy efficiency and faster response times in dynamic applications.


Choosing us as your Stainless Steel Shafts supplier means investing in a partnership grounded in technical excellence and unwavering quality. Our vertically integrated manufacturing process allows us to maintain full control over every stage, from raw material sourcing to final inspection, ensuring traceability and consistency. We employ advanced metrology equipment, including coordinate measuring machines (CMM) and laser scanners, to verify dimensional accuracy and adherence to international standards. Moreover, our engineering team collaborates closely with clients to develop custom solutions, whether for non-standard dimensions, specialized coatings, or unique material compositions. This commitment to innovation is backed by a responsive supply chain capable of meeting urgent demands without compromising on quality.

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.
