With years of experience in hydraulic piston rod manufacturing, we provide customer satisfaction through both manufacturing and customization.
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.




Unmatched Material and Heat Treatment: We utilize high-tensile strength steels and offer stainless-steel options. Our heat treatment processes, including quenching and tempering, are meticulously controlled to achieve an optimal balance of a hard, wear-resistant surface and a tough, shock-absorbing core, preventing premature failure.
Precision Chrome Plating Mastery: Our advanced hard chrome plating process is engineered for superior performance. We achieve a coating that is exceptionally dense, uniform, and adherent, providing an unparalleled combination of hardness and low-friction characteristics. This directly translates to reduced stick-slip, lower operating costs, and extended service intervals.
Peerless Geometric Accuracy: We guarantee exceptional straightness and concentricity through precision grinding. This ensures perfect alignment within the cylinder, eliminating uneven seal wear, minimizing vibration, and maximizing the efficiency and stability of the entire pneumatic system.
Robust Design and Customization: We understand that standard solutions do not always suffice. Our engineering team is equipped to provide custom Pneumatic Cylinder Piston Rods with non-standard diameters, lengths, thread configurations (conforming to standards like ISO 4395 ), and specialized end-machining to meet unique application requirements.


Selecting us as your Pneumatic Cylinder Piston Rods Supplier extends beyond procuring a component; it is a strategic partnership. Our vertical integration allows us to maintain stringent quality control over every stage of production, from raw material to final inspection. Our quality assurance protocols, which include advanced non-destructive testing and spectroscopic analysis, ensure that every rod that leaves our facility is flawless. We pride ourselves on our technical collaboration, working closely with clients to optimize designs, select materials, and solve complex engineering challenges. Furthermore, our capability to supply perfectly matched Honed Tubes creates a synergistic system that guarantees optimal performance, reduced downtime, and lower total cost of ownership for our clients.

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
