With years of experience in manufacturing Custom Hydraulic Cylinder, we provide customer satisfaction through manufacturing and customization.
At Bos, we care about you and your company. We specialize in custom hydraulic cylinder customization, material selection, and manufacturing, and provide excellent service according to your needs.




Choosing us as your Double-Acting Hydraulic Cylinder supplier means engaging with a partner that controls the entire manufacturing ecosystem. Our vertical integration, from producing raw Honed Tubes and Hard Chrome Plated Piston Rods to final assembly, guarantees uncompromising quality control, complete traceability, and consistent performance. We employ Advanced Sealing Technology, utilizing material compounds specifically selected for compatibility with various hydraulic fluids and operational temperature ranges to ensure long-term integrity. Our Comprehensive Validation Protocol subjects every Double-Acting Hydraulic Cylinder to a series of rigorous tests, including full-stroke pressure cycling and external leakage checks, to validate performance and safety before dispatch. Beyond manufacturing, we offer Deep Technical Collaboration. Our engineering team provides expert consultation on port sizing, cushioning options, rod-end configurations, and custom designs, ensuring the final product is perfectly tailored to your application's specific requirements.


Our manufacturing prowess enables us to meet a vast spectrum of technical specifications. Our standard Double-Acting Hydraulic Cylinder range typically includes bore sizes from 25mm to 400mm, with standard operating pressures up to 250 bar and high-pressure designs available for more demanding applications. The piston rods, crafted from our high-grade Precision Chrome Plated Steel Bar, are available in various diameters and feature a surface hardness typically reaching HRC 60-65. We offer a wide array of mounting styles—including foot, flange, clevis, and trunnion—to facilitate straightforward integration. To cater to diverse industrial needs, we produce several specialized types of Double-Acting Hydraulic Cylinder: the robust Tie-Rod Cylinder, known for its serviceability and conformity to international standards; the compact and rugged Welded Body Cylinder for mobile equipment and space-constrained applications; the sophisticated Telescopic Cylinder for applications requiring a long stroke from a compact retracted length; and custom Mill-Type Cylinders with integrated sensors and special coatings for extreme industrial environments.
