High-Pressure Hydraulic Cylinders | 700+ Bar Force Density

Tianjin Uranus Hydraulic Machinery Co., Ltd. is a premier manufacturer of high pressure hydraulic cylinders, engineered for applications that require maximum force in a compact package. As a “national high-tech enterprise” with over 30 years of experience, we design these cylinders to safely and reliably operate at pressures up to 700 bar (10,000 psi) and beyond, making them ideal for demanding applications such as test rigs, heavy-duty presses, and mobile equipment. Our high pressure cylinders are constructed from premium alloy steels, often forged for optimal strength, and are precision-machined to tight tolerances. We utilize advanced sealing technologies, including multiple seal profiles and backup rings, to prevent leakage at extreme pressures. The cylinder rod is induction-hardened and chrome-plated for wear resistance, and we use heavy-duty bearings to handle the high side loads that can occur in high-pressure applications. Our design process includes finite element analysis to optimize the cylinder structure for pressure containment and fatigue life. We also offer options for integrated pressure sensors, position feedback, and safety features such as burst-proof construction. Each cylinder undergoes rigorous testing, including hydrostatic testing at 1.5 times the rated pressure, to ensure integrity. For a high pressure hydraulic cylinder that delivers reliable performance in the most demanding conditions, we invite you to contact our engineering team.
