At Bos, we care about you and your company. We specialize in hydraulic piston rod customization, material selection, and manufacturing, and provide exceptional service tailored to your needs.




Selecting our Corrosion-Resistant Piston Rods translates into direct, tangible benefits for your operations and bottom line. The most significant advantage is the drastic extension of service life. By fundamentally resisting rust and pitting, these rods prevent the surface degradation that leads to seal damage and fluid contamination. This inherent durability directly correlates to reduced maintenance costs and minimized unplanned downtime, ensuring your machinery remains productive. The advanced surface finishing, often achieving a mirror-like polish, contributes to a very low coefficient of friction. This not only reduces wear on the rod itself but also significantly extends the life of costly seals and gland packings. Ultimately, this investment in superior corrosion protection enhances the overall reliability and safety of your hydraulic systems, protecting your reputation and operational continuity.


Choosing us as your source for Corrosion-Resistant Piston Rods means more than purchasing a component; it is entering a partnership grounded in technical expertise and a shared commitment to excellence. Our deep-seated knowledge in material selection allows us to guide you to the most economically efficient and technically appropriate solution for your specific corrosive challenge. We operate with a flexible and responsive manufacturing model, capable of accommodating both large-volume orders and specialized, custom-engineered rods for unique applications. Our integrated quality assurance system, which includes rigorous inspections and material traceability, provides the certainty that every rod we ship meets our exacting standards and your performance expectations. We combine this technical rigor with a global logistics capability, ensuring you receive your Corrosion-Resistant Piston Rods when and where you need them.

This can be caused by insufficient oil pressure, internal leakage, or excessive resistance. Check for low oil pressure, internal leaks at seals , or the piston rod being subject to excessive lateral loads
Ensure the axis of the hydraulic cylinder is aligned with the movement direction. The load should act along the cylinder axis to avoid eccentricity, which can cause premature wear and seizure
Seals can leak due to folding, squeezing, tearing, wear, aging, or deterioration. In such cases, the seal should be replaced
